• Catcher A.J. Pierzynski was scratched from Tuesday's lineup because of tightness in the oblique muscle in his right ribcage. Pierzynski has been out of the starting lineup in four of the last eight games while dealing with the injury.
• Colby Lewis, coming back from flexor tendon surgery, is scheduled to make his first rehab start on Thursday. He will pitch for Triple-A Round Rock against Las Vegas, and he is scheduled to pitch three innings. That will start the clock on a 30-day rehab assignment, so the Rangers will have to make a decision on Lewis within the first 10 days of June. He could be ready before that.
• Daniels said the Rangers aren't getting too caught up with what they'll have to do once Perez and Lewis are ready to come off the disabled list. Said Daniels, "If everybody is healthy and pitching well, we'll have a call to make. We're not there yet."
• Jeff Baker was not in the lineup on Tuesday with right-hander Wily Peralta pitching for the Brewers. Baker went into the game with a career .404 batting average (21-for-52) at Miller Park. That's the third highest among all players with a minimum of 50 at-bats there since the park opened in 2001.
• With all of the changes on the Round Rock pitching staff, the Rangers have moved Jacob Brigham back to the rotation. He has not allowed a run in eight relief appearances between Frisco and Round Rock this season, striking out 19 while allowing just five hits and seven walks in 14 2/3 innings.
