• Ausmus said the team has not discussed potential callups for when rosters expand from 25 to 40 players on Sept. 1. He said those discussions will likely begin when the team returns to Detroit.

• Outfielder Andy Dirks, who re-injured his left hamstring during his rehab from back surgery, has been shut down for the immediate future, Rand said on Wednesday. MRI results on Dirks' hamstring showed a Grade 1 and partial Grade 2 hamstring strain, which will come with at least a 2-4 week recovery time, and in all likelihood ending his 2014 season.

• Right-handed pitcher Luke Putkonen, who is on the 60-day DL after surgery on a bone spur in his pitching elbow, was in the Tigers' clubhouse on Wednesday. Rand said Putkonen threw a 30-pitch bullpen session on Wednesday and has been progressing well.
