Rookie Ke'Bryan Hayes leaves Pittsburgh Pirates' game with a left wrist injury; X-rays negative

CHICAGO -- Pittsburgh Pirates rookie Ke'Bryan Hayes left Saturday's game against the Chicago Cubs with a left wrist injury after taking an awkward swing in the first inning of the Pirates' 5-1 loss to the Cubs.

Hayes, 24, eventually drew a walk but then was attended to at first base after sliding back into the bag with his left hand to avoid a tag. He stayed in the game until he was pinch hit for in the third inning.

Manager Derek Shelton said Sunday that X-rays on Hayes' wrist were negative and he is considered day to day. He was not in the Pirates' lineup for Sunday's game against the Cubs.

Shelton said Saturday the knob of the bat caused the initial injury, which was aggravated on the slide into first a few moments later.

Hayes is one of the preseason favorites for National League Rookie of the Year after having a hot spring training. He homered in his first at-bat of the season on Thursday during an Opening Day win by the Pirates.
