• Twins catcher Joe Mauer, who had to cut his workout short on Wednesday due to concussion-like symptoms, worked out without any issues at Target Field on Thursday, according to Twins manager Ron Gardenhire. But Mauer didn't hit on the field, as the Twins didn't take on-field batting practice before their 8-2 loss to the A's.

• Twins general manager Terry Ryan said the club is still waiting to make a decision on whether right-hander Samuel Deduno will undergo arthroscopic surgery this offseason. Ryan said it looks more and more likely that Deduno will need to have his shoulder scoped. Deduno was placed on the 15-day disabled list with right shoulder soreness on Aug. 30, and was transferred to the 60-day disabled list on Monday.

• Entering play Friday, the Twins have 32 homers from their rookies, marking the highest total by Minnesota rookies since 1999, when they hit 42. Oswaldo Arcia leads the group with 12 homers.
