Tulo knew early that Miller was 'special' on Friday
ST. LOUIS -- When Rockies shortstop Troy Tulowitzki struck out for the third and final time against sizzling St. Louis rookie right-hander Shelby Miller on Friday night, the radar gun read 96 mph. In other words, Miller was every bit as powerful then as he was when he fanned Tulowitzki in the first inning.
Miller gave up an Eric Young single to open the game, then retired the next 27 hitters. His domination included 13 strikeouts, three of Tulowitzki, who said he knew from his first at-bat that Miller was going to be special.
"You never want to put yourself in the hands of a pitcher like that, saying we might not get a hit," Tulowitzki said. "You're looking at that next pitch or that next at-bat as, 'This is the time I'm going to get him.' You keep on telling yourself that. But you do know you've got your hands full here. He's got his best stuff and command, and it's going to be tough. You've got to put one of your best swings on one of his better pitches.
"You can just tell when a guy's got it. I knew from my first at-bat, 'Hey, this is something different.' I was walking back to the dugout after my first at-bat saying, 'He's got a little extra life on his fastball that you don't quite see that often.'"
Miller has thrown very well this season. Friday dropped his ERA to 1.58 in seven starts. But watching the previous starts on video and facing him were different experiences.
"Film never does justice," Tulowitzki said. "You can see a number -- 94 or 95. We've faced that many times, but the swings that this guy was getting last night, the ball was doing something different. He had that extra late life. He might not have that all the time. He threw one of his best games."
Rosario's positive attitude, work ethic impress Weiss
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.
Schemmel temporarily takes over radio play-by-play duties
ST. LOUIS -- Rockies radio broadcaster Jack Corrigan called Saturday's game on 850 KOA AM, but he will be away for the next two games because his brother-in-law passed away.
Jerry Schemmel, who usually shares play-by-play and color duties with Corrigan, will operate as the play-by-play man for Sunday's game against the Cardinals and Monday's against the Cubs. Root Sports Rocky Mountain pregame and postgame commentator and MLB.com columnist Tracy Ringolsby will fill in as the color commentator for the two broadcasts.
