Williams (6-8) took the loss Friday against the Cardinals, giving up four runs on four hits and four walks over 4.2 innings while striking out five.
He faced the minimum six batters through the first two innings, but the wheels started to come off after Greg Garcia led off the third with a double. Williams has been alternating dominant outings with shaky ones lately, but his 4.3 BB/9 since the beginning of August suggests the latter are more likely going forward. He'll next take the mound Wednesday in Milwaukee.
