Welington Castillo out for season

CHICAGO -- Cubs catcher Welington Castillo has a partial tear of the meniscus in his right knee and won't play over the final 10 days of the season, team president Theo Epstein announced Friday morning.

"It's the type of thing you can come back 100 percent from," Epstein said.

Castillo will have his knee scoped, and the recovery time is expected to be 4-6 weeks.

Epstein indicated that Castillo has played his way into the core of the team after a year of improvement behind the plate and on offense.

"He's always been a supertalented player and a great kid, but this has been of those years where he's really established himself and come into his own," Epstein said.

Castillo hit .271 with eight home runs and 32 RBIs but was more selective at the plate in the second half, increasing his walk totals while raising his batting average. He is considered one of the best defensive catchers in the league and, according to Epstein, improved his game-calling as well.

Castillo said Thursday he felt something in his knee while running the bases and was pulled midgame against the Milwaukee Brewers.

"It hurts when I run and catch, but mostly when I run the bases," he said at the time.
