The Rockies lost on Saturday night again to Phillies pitcher Brett Myers, who is 5-0 at Coors Field. Sunday, the Phils turn to another righty who is tough on the Rockies — Chan Ho Park, who is 5-2 in 17 games at Coors Field.

Rockies manager Clint Hurdle said Park, who has had some tough times in recent years, regained some of his form last year with the Dodgers (4-4, 3.40 ERA in 54 games, five starts).

“He really sharpened up last year, in that role of pitching one time through the lineup, and now they’re expanding it,” Hurdle said. “He’s gotten to a good place. He’s worked very hard. We know how diligent he is. We know how focused he is.

“He’s going to spin the ball. He’s going to throw the slider. One thing we feel he’s not going to pound us inside. He’ll come in for effect. I don’t think he’s so much a fastball pitcher. He’s a finesse pitcher who pitches off his fastball.”

Also, for the second time this season, the Rockies kept first baseman Todd Helton out of the linmeup for a day game after a night game. Hurdle said he’d do that, so it’s not a surprise. It’s not fun for Helton, who would put himself in the lineup every day, but Hurdle and the Rockies are adhering to a plan to keep Helton healthy throughout the season.
