Rodriguez said he hurt the thumb while fielding a grounder in the game against the Twins. He was a late scratch tonight after cutting short his batting-practice session, though he said he would be available to pinch-hit.
A-Rod went 0-for-5 Sunday in his return. In his absence tonight, the Yankees have Eric Chavez starting at third base and batting seventh. Robinson Cano has moved into the cleanup spot.
UPDATE: According to Bryan Hoch of MLB.com, Rodriguez is considered day-to-day after X-rays on his left thumb came back negative.
