BALTIMORE - Baltimore Orioles shortstop J.J. Hardy will be sidelined for at least a month with a hairline fracture in his left foot.

The injury occurred Sunday, when Hardy fouled a ball off his foot in the fourth inning against the Chicago White Sox.

Baltimore was off Monday. Manager Buck Showalter said he expected Hardy to be out 4-6 weeks.

Hardy is expected to be placed on the 15-day disabled Tuesday, before the Orioles open a three-game series against the New York Yankees.

A three-time Gold Glove winner, Hardy has played errorless ball over 22 games this season. He's batting .244 with two homers and eight RBIs.

Manny Machado will likely move from third base to shortstop during Hardy's absence. Machado has played four games at shortstop this season, including two starts.

The 33-year-old Hardy was limited to 114 games last season because of a variety of injuries.
