Padres' Tatis Jr. exits in 10th with hammy injury

WASHINGTON -- San Diego rookie shortstop Fernando Tatis Jr. left Sunday's game against the Washington Nationals after he did an awkward-looking split while trying to stretch for a throw at second base.

Tatis was unable to keep his foot on the bag on the play. He moved around gingerly while umpires reviewed the play but could not continue.

Padres manager Andy Green said after the Padres' 7-6 11-inning loss that Tatis suffered a hamstring injury. Green said it was uncertain how much time, if any, Tatis Jr. would miss with his injury.

"I think everyone saw what happened on the field,'' Green said. "So we are hoping he is OK. We'll find out in time here. He seems in pretty good spirits right now. We'll find out how severe, how mild it is here very shortly.''

The 20-year-old entered the season as one of the top prospects in baseball. He is hitting .300 with six homers and 13 RBIs for the Padres. The son of former major leaguer Fernando Tatis had a career-high three hits on Sunday.
