Perez headed for Arlington?
Martin Perez, the Rangers top pitching prospect, tweeted last night that he is headed for Arlington. There is no confirmation from the Rangers, who needed five innings from Michael Kirkman on Monday after Justin Grimm was knocked out in the second inning. The Round Rock game notes for this afternoon still list Perez as the Express starter for Tuesday.

It makes sense that the club would want another arm in the bullpen since Kirkman will be unavailable for several days, but why no confirmation?
