Pittsburgh Pirates rookie third baseman Ke’Bryan Hayes was placed on the 10-day injured list Sunday because of inflammation in his left wrist.

X-rays on Hayes’ wrist were negative but an MRI showed the inflammation, manager Derek Shelton said. Hayes was replaced in the Pirates’ lineup against the Chicago Cubs on Sunday by Phillip Evans.

Speaking during his pregame media availability, Shelton called Hayes day to day but said that Hayes experienced more discomfort while he worked out before Pittsburgh’s series finale at Chicago, so the team decided to put him on the IL as a precaution.

“Today, when we ran him through some baseball activities, it was just the squeezing of the glove,” Shelton told reporters, according to “So because of that, we decided that 10 days was more worthwhile.”

Hayes suffered the injury after taking an awkward swing in the first inning of the Pirates’ 5-1 loss to the Cubs on Saturday. 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.

Shelton said Saturday the knob of Hayes’ bat caused the initial injury, which was aggravated on the slide.

Utilityman Wilmer Difo was promoted from the taxi squad to the active roster. Right-hander Tyler Bashlor was designated for assignment to make room for Difo on the 40-man roster.

The Pirates also added right-hander Kyle Crick to their active roster and optioned right-hander Wil Crowe to the team’s alternate site. Crick had been away from the team for the birth of his child.

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 in Thursday’s Opening Day win by the Pirates.

Hayes, the son of former big league infielder Charlie Hayes, made his big league debut last summer. He batted .376 with five homers and 11 RBIs in 24 games.
