Baxter missed Saturday's game against the Cubs in Peoria and instead had a scan of the thumb, as ordered by team physician Jan Fronek. He did not play on Sunday, either.
San Diego general manager Jed Hoyer said on Sunday that Baxter will fly to San Diego on Monday to see the team's hand specialist to determine if there's ligament damage to the thumb.

"We're in a holding pattern right now," Baxter said. "I think it will be fine. If I had to bet, I'd bet it will be OK."

Baxter, who a year ago had 58 extra-base hits with Triple-A Portland before he earned a promotion, is likely set to return to Triple-A this season.
