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.
