Byron Buxton is set for exams on Friday after injuring his left wrist during Class AAA Rochester's game against Scranton/Wilkes Barre. Buxton was 0-for-1 in the game when he batted in the third inning. He fouled off two pitches, reacting as if something was wrong with his left hand after the second foul ball. He fouled off a 1-2 pitch and was noticeably in pain. He tried to wave off a trainer who came onto the field, but was taken out of the game. The Twins have been told by the Rochester staff that the injury is minor. Still, it is potentially another setback for the former top prospect as he works to return to the majors - even if he is out a couple games. Twins manager Paul Molitor confirmed that Buxton will have an X-Ray and other tests to make sure nothing serious. "It is somewhat concerning," Molitor said. Buxton had been healthy for some time after recovering from a broken left big toe, but the Twins have left him at Rochester to refine his hitting approach. Buxton began the day with a .239 batting average but was hitting .300 over his previous seven games. Thursday was the first game following the International League All-Star break. Buxton elected to remain in Rochester during the break and spent all three days at the ballpark working on his swing with Red Wings hitting coach Chad Allen. Buxton had a hamate bone scare late last season before exams revealed he only had a bruised left hand. He missed an Aug. 31 game and was back in the lineup the next day.
