On David Murphy
I feel compelled to write about this, because of the overreaction David Murphy's recent play has generated from some fans. I've seen some comments that minor league numbers don't matter if you can hit in the majors, that he's proving he can hit in the majors, that Botts and Cruz should be moved aside so that Murphy can get more playing time, and that Rudy has fixed him...
First of all, you can see Murphy's career minor league numbers here.
For those who don't want to click the link, a summary:
In high A, at age 22: 669 OPS
In AA, at age 23: 767 OPS
In AA, at age 24: 751 OPS
In AAA, at age 24: 802 OPS
In AAA, at age 25: 770 OPS
In 1902 minor league ABs, Murphy has a career 750 OPS.
Those are pretty mediocre numbers...particularly given that he wasn't particularly young for his level at any stop.
PECOTA's 50% projections over the next few years peg him at an EQA in the .240s, which would be mediocre 4th outfielder level performance. His 75% projections peg him in the .260s, which would make him a good 4th outfielder or a mediocre/weak starting centerfielder.
Since coming to Texas, Murphy has 26 plate appearances. In those 26 plate appearances, he has posted a .462/.462/.731 line. And for some reason, some fans seem to believe that Murphy's last 26 plate appearances are more indicative of what he can do than the over 2000 plate appearances he had in the majors and minors since he turned pro.
26 plate appearances doesn't tell you anything. Matt Kata hit .387/.424/.613 in his first 34 plate appearances for the Rangers this year. Ramon Vazquez hit .524/.560/1.000 in his first 25 plate appearances for the Rangers this year. Jerry Hairston Jr. hit .345/.441/.483 over a 34 plate appearance span soon after arriving to the Rangers in 2006.
Now, there is some reason to hope that Murphy could be a useful player. Murphy had a solid .299/.370/.466 line against righthanders for Pawtucket, and plays good defense, so he could be a decent platoon option in centerfield or rightfield. And he certainly could be a late bloomer, a guy who puts it together later in his career and becomes a solid regular. I'm fine with Murphy getting some ABs the rest of the way, and being in the outfield mix for 2008.
But let's quit getting worked up about his numbers so far as a Ranger. Projecting what a player can or will do based on 26 plate appearances is about as reliable as projecting based on the I, Ching or cutting open a goat and reading its entrails.
Update [2007-8-26 13:24:48 by Adam J. Morris]: -- One other point on Murphy, which I was going to make and then forgot...
Here are the pitchers he has gotten hits off of this season:
Daniel Cabrera
Edwin Jackson
Jason Hammel
Felix Hernandez
Paul Shuey
John Bale
Rob Bell
Brian Burres
Justin Hampson
Jon Switzer
Jamie Walker
Dan Wheeler
It is hard to argue that he's a better hitter as a major leaguer than as a minor leaguer when he's hitting against mostly minor league caliber pitchers...

Point taken but
i get that thats part of your point, but still... we know what they are, we dont know what murphy is. a lot of mlb players have had mediocre minor league careers and turned into nice major leaguers. not many ramon vazquez's have turned their careers around at his age. And Murphy was a high draft pick and has been a name in the boston system, even if not one of the top ones.
and its that murphy has "looked good doing it" if you know what I mean. He plays nice defense, he runs well, he seems to be able to make good contact.
Its not like because hes hitting .450 I actually believe he will hit .450.
And really, how many people have been suggesting he could be a good mlb corner outfielder? Whenever I praise him its just as someone who i think can stick around on the team in one way or another, not as a .380 hitting all star OF.

OPS
And I don't see that it is misleading in Murphy's case.
by Adam J. Morris on Aug 26, 2007 12:23 PM CDT up reply actions 0 recs
A few things...
Actually, it is half slugging % and half on-base % (OPS + Slugging). Think of it another way, (1 * OBP) + (1 * Slugging). The similar multiples (1 in this case) mean that each half of the equation is weighted equally.
"You should know that something is seriously flawed when a base hit is worth more than a walk."
Again, both are weighted equally (OBP + Slugging). There are some stat heads who dislike OPS because they feel a hit is more important than a walk (with a hit you can drive in runs, something that is very difficult to do with a walk). So, a better formula would be something like (OBP * 0.5 + Slugging). Basically, I disagree with your above assertations. However, this is not to mean that I think OPS is the greatest stat. It is flawed, though hardly a fraud.
I personally like OPS because it judges a player by his ability to get on base and to hit for power. This is the ideal player. However, these type of players are quite rare. You don't have to do get on base AND hit for power to be a good/useful player. So yes, OPS can be misleading.
"It is very possible for a person to be a dreadful ballplayer with an 800 OPS where someone else is a terrific ballplayer at the same OPS."
Well, the words "dreadful" and "terrific" are very subjective. Dunn can post a high OPS but he will rack up a lot of K's. You can argue that Dunn is not as valuable as somebody with the same OPS. For instance, adding Dunn to this current Rangers' roster might not be such a good idea as they strike out enough on their own. Yet, Dunn would be a nice fit for another team that does not strike out as often. So I see your point, but "dreadful" and "terrific" are a bit sensational.

Actually
For example a 10% increase in OBP will not have the same effect on OPS as a 10% increase in SLG.
by tricer on Aug 26, 2007 5:08 PM CDT up reply actions 0 recs
I am confuzzled....
-A hit SHOULD be worth more than a walk. A hit ALWAYS does better than a walk would (i.e., players can take extra bases on a hit, but can't on a walk).
-OTOH, a single is NOT twice as valuable as a walk, nor is a double 3x as valuable as a walk, etc. Because the most important part of getting a hit or a walk is that you did not use up an out.
-Therefore, a lot of statheads feel that SLG NOT OBP is weighted too much in OPS (though OPS is usually known as a quick and dirty method of comparing hitters, not the holy grail of tools). Some feel the weighting should be more (1.4 to 1.9)*OPS+1*SLG vs. the even division.
-A 10% increase in OBP WILL have the same effect on OPS as a 10% increase SLG. Basic mathematics assures that. Perhaps, what you meant is a 10% in BA? I dunno.

huh?
SLG is generally in the range of .400 - .600, so a 10% increase in SLG would generally increase OPS by 40-60 points.
The two numbers (OBP and SLG) are not measured on the same scale, so it is incorrect to say that they are both weighted equally in OPS.

Weighted Equally
by Excel Hearts Choi on Aug 26, 2007 5:32 PM CDT up reply actions 0 recs
Ah, I see
Still, there's a small differential between average OBP and average SLG which does make SLG more valued in OPS.
I'll concede that. I'm no longer confused about what you were trying to say.

My Formula
by Excel Hearts Choi on Aug 26, 2007 5:29 PM CDT up reply actions 0 recs
But...
As you stated a ten percent increase in Slugging is a larger number than a ten percent increase in OBP. This is why some feel that Slugging is more important than OBP; thus they should be weighted differently. Going back to my hypothetical formula of ((OBP * 0.5) + (1 * Slugging)), this would mean that Slugging is twice as important as OBP.
The difference of scales used in calculating Slugging and OBP is independent from the weight used in calculating OPS.
by Excel Hearts Choi on Aug 26, 2007 5:27 PM CDT up reply actions 0 recs
I'm still confused...
Statheads already have a problem that if you get a hit it counts in OBP AND SLG (2+).
Whereas if you get a walk, it only counts in OBP (1).
I don't see how making a single = (1.5) vs. a walk = (0.5) makes things better since a walk is already almost definitely better than 1/2 a single.

Hypothetical
by Excel Hearts Choi on Aug 26, 2007 6:12 PM CDT up reply actions 0 recs
I guess...
OPS already DOES value a hit more than a walk.
In OPS a hit is valued as 2 for a single, 3 for a double, 4 for a triple, 5 for a HR.
Whereas a walk is valued as 1 for a walk (or HBP).
Some people, however, do NOT think that the hit should be valued THAT much.
Therefore, they increase the weight TO OBP NOT SLG in more "sophisticated" versions of OPS to more accurately reflect the value of a walk vs. the hit.
As I've said, I've seen many variations on OPS where OBP is weighted anywhere from 1.4-1.9. I've NEVER seen it weighted LESS.
Is there a reason for doing this, given that OPS already values a hit >>> walk?
Req
by Requiem on Aug 26, 2007 6:19 PM CDT up reply actions 0 recs

Yes, OPS values a hit more than a walk, but it does not value Slugging more than OBP.

I disagree.
They are supposed to fulfill functions.
OPS is great as a quick and dirty method of calculating a player's value in one number.
However, it is not the most ACCURATE one. And it CAN be improved upon.
It's incorrect to argue that if you favor OBP or you favor SLG, then OPS is lacking. As one way or another will be closer to be a better gauge of a player's value. And everyone else I've talked to thinks that SLG is weighted too much in the OPS equation.
I don't disagree that OPS allows for a quick point of reference (and in fact, that's why it's used so often). But it isn't the be-all, end-all of player evaluation.

Weighting K's
I understand that K's are bad because they don't put the ball in play (allowing runners to move up, giving the defense a chance to make an error). But to an extent these negatives are mitigated by the fact that you can't hit into a double play by striking out.
Furthermore, players like Dunn (and Wilkerson) who strike out a lot force the pitcher to throw lots of pitches. In addition to the obvious (getting to the bullpen faster), it also has an effect of slowing down the game - which can make the defense less focused (basically what people were saying about Padilla). I have no idea if this is true, but do you really think that the SS is at his most alert when a "3 possible outcomes" guy like Dunn is up?
K's look bad, but when you are fielding a team with a team OBP of .323, the negatives associated with Dunn's 150+ K's are easily canceled out by the fact that when he doesn't strike out, he actually gets on base. I'll take that any day. (And before that clown comparing Dunn to Wilkerson shows up, Dunn's OBP is about 75 points higher than Wilk's...)
Bottom line - I think baseball already over-discounts some highly productive guys like Adam Dunn because of their K's, and they represent a great "buying opportunity" rather than something to be concerned about in the current market (in Moneyball terms...)

My Intention
As gp stated, two players with identical OPS's can be described as "dreadful" or "terrific", and I would argue that these subjective adjectives are probably dependent upon the makeup of the team.

if he hits anywhere close to this the rest of the season then i think he deserves a legit look at being a starter in spring training. if he proves it's just a hot streak, then oh well you gave a guy good at bats and he can be a 4th outfielder.

This is how
How a handful of at bats can overwhelm several years of contrary evidence is beyond me. Jaramillo is good, but come on. He's hardly had time to remember Murphy's name since the trade. If Kinsler is just now saying he's getting comfortable with the defensive things, don't you think it might take a little bit longer than 3 weeks for a new approach at the plate to sink in. And that's assuming that Jaramillo saw something the very first day that he could easily fix, that Carl Yastremski (who has worked with Murphy) didn't see or couldn't fix, let alone all his other coaches.

To argue that, because Botts, Cruz and Diaz have hit well in the minors, but not in the majors, that minor league numbers are irrelevant and a player with mediocre minor league numbers could put up quality major league numbers is absurd.
And Metcalf has a 719 OPS in the majors. That doesn't really support your argument.

assessment
Seems like there is an impatience on here with Botts, but I whole-heartedly agree with Adam, he needs to play everyday and be given the DH job at the beginning of next year. If he's still struggling June 1st, then consider doing something.
Murphy - somebody on here a couple of weeks ago compared him to Rusty Greer. While that would be nice, Greer basically was the same hitter in the majors as he was in the minors, except with a little more power. I think it's a shaky argument to project that a guy who hit .270 in his minor league career is going to become a .300+ hitter in the majors.

at least we have some young guys to be excited about. They need time to develop and thankfully we have the ability to be patient with them, let them get in a groove, as there's no pressure on this team the rest of this year and realistically speaking, no pressure to win the division next year.

nobody is saying Murphy is going to be our long-term answer in CF, but it sure would be nice if he could hold that spot for a few years until Boggs, Borbon, etc. are ready...assuming we don't sign a big-name free agent for CF.
question: would you rather have a guy that walks 50 times and strikes out 75 times, hits in the .280 to .300 range, plays solid centerfield and consistently puts the ball in play, or not? I think that's what David Murphy can offer us, and I'll take it.

Batting average in minors vs majors
top 7 in batting avg 2007 - career mlb average - career milb average
Ordonez - .309 - .269
Ichiro - no milb
Renteria - .291 - .258
Utley - .299 - .283
Figgins - .293 - .274
Holliday - .316 - .275
Polanco - .304 - .279
so all top 7 that played in the minors had higher major league averages, in many cases by a lot.
i was going to do top 15, but baseballcube is now lagging out on me.
i realize that choosing the top in the mlb in batting average is going to get guys that have obviously done really well in the mlb and noone who flamed out in their second, but if nothing else it shows that its not exactly this terribly rare situation.

Couple of issues...
- Like you said, you're cherry-picking the top, so you won't run into the issue where the minor-leaguers flame out. In fact, you'll likely find that the vast majority of baseball players (major and minor leaguers) have WORSE BAs in the majors than their career minor league numbers. Though, you weren't making that argument, so anyways, on to the next point.
- There's something significantly different about most of the players cited and David Murphy.
Ichiro - no milb
Renteria - 17 Rk, 18 A-, 19 A+, 20 AA, 21 AAA/MLB, 22 MLB
Utley - 22 A+, 23 AAA, 24 AAA/MLB, 25 AAA/MLB, 26 MLB
Figgins - 19 Rk, 20 A-, 21/22 A+, 23 AA, 24 AAA, 25 AAA/MLB
Holliday - 18 Rk, 19 A-, 20/21 A+, 22/23 AA, 24 MLB
Polanco - 18 Rk, 19 A-, 20 A+, 21 AA, 22 AAA/MLB, 23 AAA/MLB
Murphy - 21 A-/A+, 22 A+, 23 AA, 24 AA/AAA, 25 AAA/MLB?
Almost all the other players were at least pretty young for their level in SOME part of their minor league listing. And all of them had were at least part-time players in the majors by age 24 or earlier (except Figgins and Ichiro was in Japan).
Not only that all but one of the cited players have shown the ability to hit > .300 over a significant amount of time in the minors or were extremely young for their level. And the one exception is due almost entirely to the Coors effect, IMO.
Best seasons
Ordonez - .329 in 523 AB (AAA)
Ichiro - no milb
Renteria - .289 in 508 AB as 20yo (AA)
Utley - .323 in 431 AB (AAA)
Figgins - .305 in 511 AB (AAA)
*Holliday - .276 in 463 AB (AA)
Polanco - .291 in 508 AB as 21yo (AA)
Murphy - .280 in 400 AB as 25yo (AAA)
Of course, we're really just quibbling. I don't think anyone here really thinks that Murphy is definitely going to be a starting OF for a playoff team just because of these 28 PAs. Nor does anyone really think that Murphy has no possibility of improving.
But the quibbles are what we baseball fans like to argue about.

Aside from all the hard facts (stats), there might be a little bit of incentive for Murphy to earn a starting spot by next year. He was born in Houston, grew up there and went to Baylor. Now, he is married and his wife is from Dallas as is all of her family. Not to mention, they have a newborn...this to me says he will work a little harder to earn a spot because he is in a perfect situation. Just something to think about...
