Worth noting

• For the first time since undergoing surgery to repair a ligament tear in his right thumb, Yadier Molina took light swings in the batting cage on Wednesday. He also took the field to do some throwing with a less-restrictive cast. Manager Mike Matheny described the ball as "jumping out of his hand." Matheny said the Cardinals had still not determined whether Molina would accompany them on this road trip or remain in St. Louis for rehab.

Michael Wacha (right shoulder stress reaction) threw a bullpen session, as scheduled, on Wednesday afternoon. It marked the third time Wacha has taken the mound since being cleared for this next step in the rehab process.

• After delivering key RBI doubles in the first two games of the series, Daniel Descalso earned a spot in the starting lineup for just the third time since July 6. Descalso, 7-for-20 this month, started in place of Kolten Wong at second base. With Wong, the team's usual two-hole hitter on the bench, Jon Jay moved up to bat second in the order.

• Reliever David Aardsma was activated off the disabled list on Wednesday and added back to the Triple-A roster. Aardsma missed 50 games after going on the DL on June 17. He recently made two rehab appearances with the Rookie-level Gulf Coast League affiliate and allowed one run on three hits while striking out two in two innings.
