Last night, it was reported in the Twitterverse that righthanded pitcher Mark Hamburger was pulled from his start last night after just one inning, and was congratulated and high-fived by his teammates in the dugout. The speculation was that Hamburger, expected to be a September 1 callup when rosters expanded, was getting the call early and being brought up to Texas.
Norm Hitzges has apparently reported on the Ticket that the Rangers are purchasing the contract of Hamburger, who would presumably join the Rangers' bullpen prior to tomorrow's start by Scott Feldman.
Hamburger, acquired from the Minnesota Twins in exchange for Eddie Guardado in August, 2008, has put himself on the prospect map with a solid season this year. He started out in AA Frisco, and posted a 1.83 ERA in 19.2 innings while striking out 10 batters per 9 and walking 2.3 per 9.
Since moving up to AAA Round Rock, Hamburger has posted a 3.88 ERA in 62.2 innings, with 6.9 K/9 and 2.9 BB/9. Although Hamburger had spent his entire career as a reliever, the Rangers recently moved him into Round Rock's rotation, and he's started four games for the Express.
Hamburger, 24, is not on the 40 man roster, so the Rangers will have to create a roster spot by making a move with someone on the 40 man roster. Wilmer Font could be recalled and put on the 60 day disabled list, or the Rangers could put Ryan Tucker or Tim Wood on waivers to open a roster spot.
The other question is, what moves with the Rangers make with their 25 man roster to clear space for Hamburger and Leonys Martin, also being recalled. My guess, just off the top of my head, is that Matt Harrison will be put on the 15 day disabled list with a "dead arm" or something like that -- Harrison last pitched on August 24, so he would be eligible to be activated on September 8.
Nelson Cruz could be headed to the disabled list, as well, if the Rangers are convinced he won't be ready anytime soon, although I'd be mildly surprised if they actually did that with the September 1 roster expansion coming on Thursday.
Darren O'Day or Yoshinori Tateyama could also be optioned to make room for Martin and/or Hamburger on the active roster.
