"Where Ian Stewart provided power, Melvin Mora brings a presence. Where Stewart could change a game with one swing, Mora might start a rally with an eight-pitch walk.

Stewart is making progress from his right rib-cage injury and could be available a week from today at Arizona.

Until then, Mora continues to hold down third base for the Rockies, starting regularly at age 38 — as if he swan-dived into the Fountain of Youth.

"I feel good. I have to be ready for whatever they need me to do. But Ian is the third baseman," Mora said humbly before Monday night's game. "I am here to help him."

Mora has made 14 starts since Stewart landed on the disabled list, hitting .280 with a home run and three RBIs. Manager Jim Tracy calls him "the consummate pro," and the Rockies' young Latin players praise his influence.

After struggling early in the utility role, Mora became more comfortable with life in the National League. He has helped provide more balance to the Rockies' lineup, particularly against left-handers, whom he has hit at a .305 clip.

"I focus on getting on base, especially with runners on. You have to be ready to hit, but not be afraid to pass it on to the next guy and let him be the hero," Mora said."
