SCOTTSDALE, Ariz. -- Infielder Alfredo Amezaga had the look of a man who was saying goodbye, if only temporarily.

Amezaga and first baseman Mike Jacobs were the latest Rockies to be reassigned to Minor League camp on Monday.

Amezaga, 33, who has had 80 combined at-bats in the Majors and Minors since the end of the 2008 season, and is coming off microfracture knee surgery, was a revelation this spring. After being given the early part of Spring Training to complete his recovery, Amezaga, a super-utility player for the Marlins from 2006-08, hit .294 with a double and a triple in 11 Cactus League games as a non-roster invitee.

The Rockies believe Amezaga needs regular action at Triple-A Colorado Springs to reach both full health and effectiveness. He can play several infield and outfield positions, and in his short time in camp he proved he is the team's best defensive alternative should star shortstop Troy Tulowitzki become injured.

Amezaga said he never considered asking the Rockies to allow him to seek another Major League job.

"I'm good, and it depends on the situation, and whatever happens I'll be able to help the team in any way," Amezaga said. "I love it here. I want to finish my career here. For me, if you play this game correctly -- right and hard -- you're not going to have problems."

Jacobs, 30, who played for the Mets, Marlins and Royals before joining the Rockies as a non-roster invitee, hit .205 with one home run and six RBIs in 23 Cactus League games. Jacobs was signed as insurance in case of an injury to regular first baseman Todd Helton.

The Rockies head into Tuesday's Cactus League finale against the Mariners at Salt River Fields at Talking Stick with 28 players still in camp, and must be down to 25 by Opening Day. One is pitcher Aaron Cook, who will begin the year on the disabled list with a fractured right ring finger.

An option for the Rockies, who are expected to add Jason Giambi (under a Minor League contract) to the Opening Day roster, would be to place Cook on the 60-day disabled list, which removes him from the list of 40 who are eligible for Major League play until he is activated. Another way to clear a spot for Giambi would be to remove a player being sent to the Minors from the 40-man roster.

In addition to Giambi, the non-roster invitees still in camp are outfielder Willy Taveras, who is sizzling at .350 this spring, but might not have a spot in a four-man outfield, and catcher Matt Pagnozzi, who is competing with Major League roster member Jose Morales for the backup catching spot. If the Rockies choose Pagnozzi, they would likely have to remove Morales from the Major League roster.

Reynolds will be entrusted with key matchups

PEORIA, Ariz. -- Matt Reynolds became the Rockies' most dependable left-handed reliever immediately after being promoted from the Minors last August, and he is looking like that guy again going into 2011.

Reynolds, 26, continued his strong finish to the spring by throwing a scoreless inning with one strikeout in the 7-6 loss to the Mariners on Monday afternoon. After giving up three home runs in his first four Cactus League games, and a homer in a 'B' game during that stretch, Reynolds has held opponents to one run and three hits in four appearances since.

Even during his rough stretch, it wasn't as if he was wild. Essentially, one pitch was tripping him up each time.

"I feel pretty comfortable heading into the season, throwing the ball pretty close to how I'm capable of throwing it," Reynolds said. "These guys are professional hitters, so if you throw any kind of mistake, they'll make you pay for it."

It looks as if Reynolds will be held for key matchups later in the game. Franklin Morales, the other lefty in the bullpen, started the spring smoothly but has had issues falling behind hitters -- especially the first hitter -- late in camp.

Reynolds, a 20th-round pick out of Austin Peay State (Tenn.) in 2007, made the climb by sticking with his strengths.

"Because I'm tall and the way the ball comes out, I've got the good angle going," said Reynolds, who is listed at 6-foot-5. "My arm angle is the most deceptive part of my delivery."

Stewart not worried about hamstring tightness

PEORIA, Ariz. -- Rockies third baseman Ian Stewart said before Monday's game with the Mariners that he was surprised at how good he's felt since missing 15 days earlier this spring with a right knee sprain. But he did deliver a warning.

"I'm really pleased with how quickly I got my timing back in the batter's box, especially having not played or really been on the field," Stewart said. "But there's just a little tightness. But 'Doogie' [Rockies head athletic trainer Keith Dugger] told me that I'd be able to feel it through the first month of the season. It's more of a reminder."

The reminder came in the form of left hamstring tightness, which he suffered during his seventh-inning double in the 7-6 loss to the Mariners.

Stewart has hit .200 with three RBIs, but it's only in 25 at-bats over nine games. Manager Jim Tracy has been happy with Stewart's hitting approach, such as on his hit after Seth Smith stole second. Now he is hoping there isn't a setback.

"Right now it's a cramp and we'll know more tomorrow," Tracy said Monday afternoon. "You've got to give something like that a night. The tests that they did for damage to the hamstring, they see nothing significant."
