Pennington is out of the lineup Sunday against the Tigers.
This will be the third time in the last four games that Pennington has taken a seat, as Kaleb Cowart will now have started at the keystone in back-to-back contests. Pennington's August performance at the plate hasn't done him many favors -- he has just one base hit in his last six games, and is just 9-for-56 on the month, striking out 23 times.
