Mets' Tatis done for year after separating right shoulder in loss to Nats

WASHINGTON -- New York Mets outfielder Fernando Tatis is out for the season after separating his right shoulder in the fifth inning of Tuesday night's game against the Washington Nationals.

Tatis was hurt when he attempted to make a diving catch on pitcher Odalis Perez's double. Tatis landed on his shoulder and stayed on the ground as the ball rolled past him for a double. He was replaced by Nick Evans.

New York manager Jerry Manuel said Tatis would not return during the regular season or for a possible playoff run.

"He's done," Manuel said after his team's 1-0 loss. "That's very discouraging, to lose a big piece of where we are and what we've accomplished so far."

A pleasant surprise since coming up from the minors, Tatis batted .297 this season with 11 home runs and 47 RBIs. He did a nice job filling in for injured outfielders Moises Alou and Ryan Church.

Losing Tatis hurts the Mets, who fell out of first place in the NL East, a half-game behind Philadelphia. New York also is missing second baseman Damion Easley (quadriceps), another productive right-handed bat.

"When we lose Tatis, we definitely have to reassess where we are offensively," Manuel said.
