De La Rosa unlikely to make Monday's start

PHOENIX -- Rockies left-hander Jorge De La Rosa probably will not make his scheduled start on Monday against the Cardinals at Coors Field because of a sore left thumb, manager Walt Weiss said.

"On De La, yeah, it looks like he's not going to go on Monday," Weiss said prior to Saturday night's second game of a three-game series against the D-backs at Chase Field. "We've got to decide who's going to make that start. We haven't figured that out yet. But it doesn't look like he's going to be able to make his start Monday."

De La Rosa left Tuesday's start against the Giants in San Francisco during the second inning with left thumb and index finger discomfort. He continued to have pain during a bullpen session before Friday's 7-5 Rockies victory at Chase Field.

The thumb has been a chronic problem for De La Rosa throughout a season in which he's 16-6 with a 3.49 ERA in 30 starts. He's 8-1 since July 10.

"I've been pitching like that for something like two months," De La Rosa said. "In the last game, it started to bother me a little more than normal. I feel fine. I told them I can be ready for my next start so we'll see."

Weiss said that with 14 games left in the regular season, he wasn't ready to say that De La Rosa wouldn't pitch again. Monday's start will likely go to someone from a group that includes Jeff Francis, Jeff Manship and Chris McHugh.

"We're not sure how much we'll push him back," Weiss said about De La Rosa. "We haven't gotten as far as shutting him down for the season yet. Just push back his start a little at this time. We have guys down there in the 'pen, who have made a number of starts so we wouldn't have to piece it together."

Time running out for CarGo to return

PHOENIX -- The Rockies haven't shut down Carlos Gonzalez from hitting for the remainder of the season, but they are perilously close to doing so with two weeks to go.

Gonzalez is suffering from what the club is calling a sprained joint in his right middle finger and hasn't had a plate appearance since Aug. 2.

"I'm not willing to say that yet -- that he's not going to swing the bat again," said manager Walt Weiss prior to Saturday night's game against the D-backs at Chase Field. "But it's getting to a point where we're getting pretty close here. I don't know if it's worth it to possibly set him back [as he goes] into the offseason."

Gonzalez displayed the swelling in the knuckle before the game and it hasn't appreciably gone down since he did the same thing this past weekend in San Diego. Gonzalez said there's a torn ligament in the area and that he's contemplating surgery.

He was reinstated from the disabled list on Sept. 3 and has only seen action in six games since as a late-inning defensive replacement in the outfield.

"I'm doing my treatment, hoping it will get better," he said. "But we're still seeing a lot of doctors, a lot of hand specialists to see what they think and whether surgery is needed. Some say yes, I need surgery, others say no. It's not getting any better. I can't grab a bat or anything. They tell me to just let it calm down. Hopefully it will get better."

Largely because of the hand injury, Gonzalez has played in only 109 games. He's batting .302 with 26 homers and 70 RBIs. At nearly 28, he's four years removed from his best season when he led the National League with a .336 batting average, 197 hits and 351 total bases in 145 games.

It's clearly frustrating.

"It is very much so," he said. "I'm used to playing every day. Not being able to swing the bat is one of the toughest parts for me. Not being able to play. That's what I love to do: go out there and compete every night. When I can't, it's very frustrating."

Rockies call for caution, aid during Colorado floods

PHOENIX -- An incessant storm that has pelted the Denver area all week with rain and hail, causing wide-spread flooding, led the Rockies management to issue a statement on Saturday urging residents to exercise caution.

"The images emerging from Colorado the past few days are a terrifying reminder of how quickly our communities can be overwhelmed," club owner, chairman and chief executive Dick Monfort said. "We are deeply saddened by the deaths and destruction caused by the horrific floods, and are so concerned for the residents of those communities, their families, their homes and their businesses. Our hearts and prayers go out to everyone that has been affected."

The Rockies asked fans to join with the State of Colorado and the affected communities to make a donation in support of the American Red Cross Disaster Relief Fund by visiting http://www.redcross.org, by calling 1-800-RED-CROSS or by texting the word REDCROSS to 90999 to make a $10 donation.
