SCOTTSDALE, Ariz. -- Tyler Colvin joined the Rockies last year with the task of proving he was a Major League player. The Cubs, after all, had sent him to the Minors for a good portion of 2011 and unceremoniously traded him during the winter.

Colvin reestablished his career by hitting .290 with 18 home runs and 72 RBIs for the Rockies while playing all three outfield positions and first base. The production earned him a one-year, $2.275 million contract in his first year of arbitration.

But Colvin, 27, who had a strong rookie year with the Cubs before struggling through 2011, realizes he's still at the proving stage of his career.

"We've got a whole new staff and everybody has to see what I can do," Colvin said. "I'm going to get ready for the season, and whatever happens, happens.

"Every year you have to prove yourself. Just to have that bounce-back year is good, just to know I can get back to where I should be, go back to the right approach and the right mindset at the plate. From there, it's just having good at-bats. It really worked out for me."

Weiss sees Young as potential 'super-utility guy'

SCOTTSDALE, Ariz. -- New Rockies manager Walt Weiss' stated goal of increasing his team's versatility and aggressiveness on the bases could be a boon to the fortunes of Eric Young Jr., who was second on the team with 14 stolen bases despite playing just 98 games last season. Many of Young's appearances were in a reserve role.

Young, 27, spent most of his Minor League time at second base but began working in the outfield in 2009, the year he debuted in the Majors. Last season, when he finished with a .316 batting average, he made 34 appearances in the outfield and none in the infield.

"He's primarily an infielder," Weiss said. "But I see him -- especially for his career, and for us -- if he could be a super-utility type guy, where he can play some second and play some third. We're not going to just throw him in there. He's going to run around the infield, take some ground balls, see what that looks like and how he feels. Maybe that's an option for us, to get what he does in the lineup."

If the infield work goes well in practices, Young will see action in the infield in Spring Training games.

Corpas and son 'Mac' happy to be back with Rox

SCOTTSDALE, Ariz. -- Manny Corpas' unforgettable 2007 season for the Rockies truly stuck with his young son, Manny Allan, or "Mac." Elbow problems led to surgery that cost Corpas the 2009 season, and his eventual departure from Colorado. But as far as Mac Corpas was concerned, his dad never left.

"When I signed with Texas in 2011, every time he wanted to go to the field, I said, 'No problem,' but he wanted to go wearing a Rockies hat or a T-shirt with 'Rockies' on it," Corpas said. "I said, 'No, you can't wear it.' He'd say, 'But I like the Rockies.' He was a little confused.

"Last year when I was with the Cubs, it was the same thing. He'd want to come to the clubhouse wearing a Rockies hat. This year, I asked him, 'Would you like for me to sign back with the Rockies?' Now he's so happy."

After going 0-2 with a 5.01 ERA in 48 relief appearances for the Cubs last season, Corpas, 30, re-signed with the Rockies on a Minor League contract. He and his wife, Amy, plus Mac and his baby sister, Elyana, continued to live in the Denver area as Corpas attempted to rebuild his career.

Believing that Corpas is at a time when he could be fully healthy and effective, the Rockies signed the right-hander to compete for a hybrid relief role, in which he can replace the starter and face one batter or pitch multiple innings.

Corpas said he felt healthy last year and even better this year. The sight of No. 60 in purple pinstripes might have fans dreaming of past glory, when Corpas took over for Brian Fuentes as closer for the latter part of the season and earned 19 saves, plus five more in the postseason. Corpas, for his part, said he is looking ahead.

"When I go to sleep, I go to sleep," Corpas said. "Everybody thinks I'm crazy, but for me that's in the past, 2007. I'm fine. I'm good. What I do is think of what I have to work on. It's not easy to make 2007 happen again.

"The fastball, I can't tell you how fast, but it's good. My sinker is good, my slider, I'm trying to get that back, and I'm getting closer."

Pacheco impressing staff with work behind plate

SCOTTSDALE, Ariz. -- Reports on versatile Jordan Pacheco's work at catcher -- both before Spring Training and in Rockies camp -- are encouraging. With the club looking for ways to keep his bat in the lineup, that's good news.

"That's an interesting question, because he's really good," catching instructor Jerry Weinstein said. "I don't know. It's going to be a very competitive environment, so we will have to see how things shake out."

"He can really catch and he can manage a ballgame, and his throwing is much improved and he's a better technician."

The Rockies most likely will carry two catchers -- Wilin Rosario as the starter and a veteran such as Ramon Hernandez, or possibly non-roster player Yorvit Torrealba.

Pacheco, who received regular starts at third and first base last season and led National League rookies with a .309 batting average, is an option to go behind the plate late in games or as a starter.
