Rangers put Pierzynski on 15-day DL
Pierzynski was a late scratch before the Rangers' game Tuesday in Milwaukee and sat out again Wednesday after the test.
Pierzynski, 36, was hitting .263 with four home runs and 11 RBIs in 26 games for the Rangers, who signed him to a one-year contract last December. The 16-year veteran has been on the disabled list only one other time in his career, missing 17 games due to a fractured left wrist in 2011.
With a day off scheduled Thursday, the Rangers are expected to summon catcher Robinson Chirinos from Triple-A Round Rock before their next game, Friday at Houston.
