ST. LOUIS -- Rockies catcher Wilin Rosario was not in the lineup Saturday because it was a day game after a night game, but it could also have been a necessary break. Rosario entered Saturday 3-for-28 (.107) since May 1.
Rosario, who was replaced by Yorvit Torrealba on Saturday, said keeping things simple is the only way back.
"Hitting isn't easy," said Rosario, who has seven home runs, 19 RBIs and a .287 average. "You just have to keep your mind fresh. I can't afford to think a lot about it, because I have to concentrate on my defense.
"When I've got a bat, I think about my offense. When I've got a mitt, I think about my defense. You've got more time to think about your defense because you're behind the plate for nine innings, and you may bat four times in a game."
Rosario has improved defensively after a rough rookie year in 2012, but still has room to develop. His ability to bounce back after tough games and have an impact offensively is a trait that impresses manager Walt Weiss. He believes Rosario will develop into a star.
Weiss also thinks that Rosario is handling the slump well.
"He's going to be a guy that hits for power, hits for average and be an offensive force in this league for a long time," Weiss said. "He brings a lot of positive energy every day. He's got a great attitude, a great mentality for this game.
"He smiles a lot, and that's good. He's very comfortable in his own skin, a very confident player. His teammates like him. He brings a lot."
Because Torrealba started Saturday, Weiss said he planned to start Rosario on Sunday with left-hander Jorge De La Rosa pitching. Torrealba has caught all seven previous starts of De La Rosa (3-3, 3.52 ERA), and the two have meshed well.
