SCOTTSDALE, Ariz. -- Nolan Arenado sees this Spring Training camp as an opportunity. If he takes advantage of it the way he's done others recently, he could find his way to Coors Field soon enough.

"I'm not going to see it as anything more than that," Arenado said. "It's an opportunity to show them what I have, get to know some people and hopefully one day play with them."

Arenado, the club's top prospect, according to MLB.com's Prospect Watch, is just 20 years old and is perched next to veteran third baseman Casey Blake -- the club's likely Opening Day starter -- in the clubhouse at Salt River Fields at Talking Stick.

The second-round Draft pick (59th overall) in 2009 made his mark this fall in the Arizona Fall League, where he was named the league's MVP after finishing among the leaders in several offensive categories. He also led the Minors in RBIs this year, with 122 in the California League.

"It's been hard work in the offseason and hard work during the season," Arenado said. "I'm trying to be one of the best, and that's my goal and I'm trying to work as hard as I can to be the guy that makes it to the big leagues and stays in the big leagues. I don't want to go up and down. I want to be in the big leagues and be there for a while."

For those reasons, along with the sturdiness of Blake and a few other options at third in the meantime, it's unlikely Arenado will be a regular contributor until 2013. But he has every intention of getting his money's worth while he's got the eyes of the organization on him in Scottsdale.

"I'm coming in here to play as hard as I can and try to win a spot," Arenado said. "I don't know if the chances are high or not, but it's still the goal, automatically."

Betancourt won't change approach in new role

SCOTTSDALE, Ariz. -- Rafael Betancourt's role in the Rockies' bullpen this year is drastically changing. But the reliever is adamant his approach will not.

The 36-year-old right-hander is entering his 10th career season in the big leagues -- fourth with Colorado -- but his first as a full-time closer. He will be taking over for Huston Street, who was traded to the Padres in December.

"You don't have to change anything," Betancourt said. "Even last year, the six weeks I closed, I didn't change anything I did. Every time I came to the field the same, and this year won't be any different."

When Street was injured at the tail end of last season, Betancourt stepped into the role and racked up a career-high eight saves. He has at least one in each of his nine big league seasons.

Betancourt was traded to the Rockies before the Trade Deadline in 2009 and was instrumental in helping Colorado to the playoffs that season. He is 10-2 with a 3.00 ERA and 191 strikeouts in 150 innings of work for Colorado.

And though Betancourt may add a few saves to those statistics, he doesn't plan to change the way he goes about getting them.

"I don't really want to do that, because that means you're going to put more stuff in your head," Betancourt said. "And I don't want that."
