Tracy sets early Cactus League rotation

SCOTTSDALE, Ariz. -- Ace right-hander Ubaldo Jimenez will start the Rockies' Spring Training opener, on Saturday against the D-backs, in the inaugural game at Salt River Fields at Talking Stick.

Left-hander Jorge De La Rosa will pitch in an intrasquad game on Sunday, and righty Jhoulys Chacin will face the D-backs in the team's second Cactus League game, on Monday.

Colorado's other two starters, right-handers Aaron Cook and Jason Hammel, have not been slotted. Cook has not thrown for two days because of tightness in his throwing shoulder and a stomach bug, but expects to return to playing catch on Tuesday.

Cook hopes to resume throwing on Tuesday

SCOTTSDALE, Ariz. -- Right-hander Aaron Cook did not throw on Monday for the second consecutive day, but he should return to playing catch on Tuesday.

Cook skipped Sunday's session because of tightness in his throwing shoulder. In addition to resting the arm on Monday, he dealt with a stomach bug as well.

"It's just normal inflammation in the shoulder," Cook said. "It varies. This time it's early [in camp]. It's usually a little later. It's just something that came up, and we're going to take care of it."

CarGo carrying a little extra cargo

SCOTTSDALE, Ariz. -- Outfielder Carlos Gonzalez reported to Spring Training weighing 222 -- 22 pounds more than he weighed at the end of last season -- in hopes of finishing stronger.

Gonzalez didn't exactly limp to the finish. He led the National League with a .336 batting average and came in third in the NL Most Valuable Player voting. His power numbers diminished toward the end of the campaign, but that was because he played the final 29 games with tendinitis in his right wrist and thumb.

That's not weight-related, but he was tired, and he might have struggled had the Rockies advanced to the playoffs. He would like to finish the 2011 season weighing in the 215 range.

"I want to keep my body strong until the end," said Gonzalez, who is beginning a seven-year, $80 million contract this season. "We were thinking about the season, but we're also thinking about the playoffs. We want to go all the way to November, so I want to be as healthy as I can. That was my mentality.

"I was worn down. When I was at 200, that's when you start feeling a lot of pain in your body. I want to keep healthy all the way to the end this year."

Said manager Jim Tracy: "It's all good weight. That's a man's body, no question about it."
