The Rangers shortened Mark Hamburger's start on Sunday for Triple-A Round Rock to one inning so that he could be available this week. He's likely to be called up, though no final decision has been made yet. The club has not decided on position players, opting to wait for results of the MRI on Nelson Cruz's left hamstring, which he strained on Sunday.
Laugh at Hamburger's name if you want, but he's put up solid numbers. The 24-year-old is 8-4 with a 3.39 ERA in 82 1/3 innings at Double-A Frisco and Triple-A Round Rock this season. He was moved into the starting rotation on Aug. 12 and has responded. He's 2-0 and has given up two runs on nine hits with 14 strikeouts and three walks. That's in four starts, though one was the 1-inning outing last night (had a K and no hits in that inning).
Hamburger is not on the 40-man roster, so the club would need to make a move (that's not difficult in that someone could go on the 60-day DL or be put on waivers).
Hamburger came to the Rangers when the traded Eddie Guardado to the Twins in August, 2008. Hamburger has a great story, BTW, signing a contract with the Twins on an open tryout. I talked to Hamburger about that before the season started and it's an interesting story.
