SCOTTSDALE, Ariz. -- The Rockies' interest in pitcher Guillermo Moscoso lies not just in the one thing he could do well, but in the variety of options they have with the right-hander.

Moscoso came over in the January trade with Oakland that sent Seth Smith to the Athletics and brought Moscoso and Josh Outman to Denver. Moscoso is one of a multitude of pitchers who will factor into the rotation competition, but could also prove to be a valuable long man out of the bullpen.

"He's competing," manager Jim Tracy said. "He's competing for a spot on this team."

In three big league seasons (two with Texas, one with Oakland), 21 of Moscoso's 34 appearances have been starts. He's 8-10 with a 3.47 ERA, averaging 5.6 strikeouts per nine innings.

"He's one of those guys that kind of falls into that mix of, does he end up being one of our guys coming out of Spring Training that's going to pitch every fifth day?" Tracy said. "Or does he fall into that mold of being one of those guys in your bullpen that has the potential of pitching multiple innings? Because we are hunting for a couple of those."

Moscoso -- who has the reputation of being a fly-ball pitcher, which could hurt him at Coors Field -- posted career-best numbers in nearly every relevant category last season, largely thanks to a cut fastball he developed in Oakland. If he can harness it with Colorado, it could be the key to his success.

"I've got more to go," Moscoso said. "That's why they brought me here. They know I can pitch. They know I'm one of those guys that if I get the ball every five days, I'll compete for my team and fight for my team."

Hitters among those offering pitching advice

SCOTTSDALE, Ariz. -- As Rockies pitchers throw to hitters for the first time in live batting practice early this week, they'll be surrounded by instructors offering advice and criticism. That includes the hitters they're facing.

"It's more about the pitchers than the hitters," Rockies outfielder Carlos Gonzalez said after facing 24-year-old right-hander Jhoulys Chacin. "We want to see a couple pitches, but we want to see them work."

About a dozen pitchers threw in the first full-squad workout on Monday, including newcomers Jeremy Guthrie and Guillermo Moscoso. Youngsters Alex White, Drew Pomeranz and Chacin also threw to hitters. Each of the aforementioned hurlers will compete for a spot in Colorado's Opening Day rotation.

"You're basically just asking about consistency," White said of the feedback from hitters. "Any hitter, either now or during the season, is looking for inconsistency in your delivery, so a lot of it has to do with what they see in terms of delivery, arm slot, things like that."

Catcher Ramon Hernandez was able to help Guthrie after Hernandez lined a shot to the left-field wall off Guthrie, just as Jason Giambi counseled Moscoso on his arm angle during his session.

"We're all working here," Gonzalez said. "We're all trying to get better, and the more you can help your teammates, the better."
