Thoughts on a 3-2 Rangers loss

Twins 3, Rangers 2

• When you score only two runs, you're generally going to lose.  The offense bears some blame for this.
• That said...you got 5.2 scoreless innings from Yovani Gallardo.  You went into the bottom of the 8th with a 2-0 lead.  And you let Jake Diekman cough up the lead on a day where he clearly didn't have his command.  That's maddening.
• Diekman has apparently been anointed the 8th inning guy, as Sam Dyson got the final out of the 6th and Keone Kela pitched the 7th.  And he's had success since coming over in the Cole Hamels trade...but he's also the guy who had a 5+ ERA for Philly this year, and who walks a bunch of batters.  From the time he entered the game today, Diekman's command was poor.  He walked the leadoff batter, got a fly out, and then saw Brian Dozier yank a pitch down the left field line that just barely went foul, a foot or two away from being a homer.  Dozier then ripped a ball into the gap in left-center that Delino DeShields made an exceptional play to run down for the second out.  Joe Mauer, a lefty, ripped a double to bring home a run, and brought righthanded hitting Miguel Sano to the plate.  Rather than going to a righthanded reliever, however, Jeff Banister stuck with Diekman, and Diekman gave up a blast that barely stayed in the park, tying the game at 2.  Spencer Patton was then brought in to get the final out, but the damage was done.
• Patton then went on to issue a two out walk to Kurt Suzuki in the 9th, and then allow a walk-off double.
• Here's what I don't get, though...how do you, as a manager, decide that Shawn Tolleson can throw two innings on Saturday because you don't trust anyone else to close out a game where you have an 8 run lead, but not be prepared to get Tolleson in the game to face Sano, a righthanded hitter who represents the go ahead run, with two outs in the 8th today and with a one run lead?
• Meanwhile, the offense did very little.  Elvis Andrus had a two run home run for the only runs of the game.  That's not good enough.  And yet, it was almost enough to win.
• Frustrating.
