Ailing hamstring keeps CarGo out of Rockies' lineup

SAN FRANCISCO -- Rockies left fielder Carlos Gonzalez was scratched from the lineup for Tuesday night's game against the Giants after testing his sore left hamstring during the afternoon.

Gonzalez didn't start Monday night but grounded out -- and didn't look good running down the first-base line -- in the ninth inning. The lingering soreness and the brisk weather in San Francisco led to the decision not to start him Tuesday.

"I ran and it didn't go well, so that's why they took me out," said Gonzalez, hitting .307 with 22 home runs and a team-high 85 RBIs in 131 games. "If I'm not 100 percent, they don't want me to play. I'm like 60-65 percent. Being here doesn't help because of the weather."

Gonzalez said the hamstring should heal in time for him to play before the end of the season.

Also, the Rockies gave rookie second baseman Josh Rutledge the night off Tuesday to rest a sore left quadriceps. Rutledge labored while running out his RBI triple in Monday night's 2-1 loss to the Giants.

Cuddyer's generosity garners Clemente Award nod

SAN FRANCISCO -- Rockies outfielder Michael Cuddyer, who made a hospital visit to victims of a tragic movie theater shooting in Aurora, Colo., and has done many charitable deeds in Denver and his former home, Minnesota, is the Rockies' nominee for the 11th annual Roberto Clemente Award, presented by Major League Baseball and Chevrolet.

The Rockies made the announcement Tuesday.

Cuddyer said he has elected to earmark the $7,500 donation that Chevrolet has made in his name -- which the company does for each of the 30 club nominees -- to giveSPORTS, a project of A Precious Child Inc., which supports children in Colorado. The giveSPORTS program provides sports equipment for families that might not be able to afford it. Cuddyer was moved to make the donation because aspiring sports reporter Jessica Redfield Ghawi, who was killed in the July 20 mass shooting, was active in supporting the foundation.

A Precious Child Inc. has established the Jessica Redfield Ghawi giveSPORTS Scholarship Fund to cover the costs of registration, league and tournament fees, sports equipment and related expenses so children will have the opportunity to participate in organized sports.

"I was lucky enough to be nominated for this before, and I gave to an organization that did the same type of thing, gave sports equipment to kids or organizations that couldn't afford equipment," Cuddyer said. "I found out that she had started her own program for this."

Cuddyer also has committed to donating a larger gift that Chevrolet gives to the winner of the award -- which will be announced during the World Series -- to giveSPORTS.

In addition, upon signing with the Rockies during the offseason, Cuddyer purchased a suite at Coors Field where he hosts children from all walks of life, and he has donated school supplies to children in need.

"We are in a position where we can give back in a lot of ways, whether it be money, whether it be time, whether it be the fame and fortune that you have to be able to raise awareness for certain causes," Cuddyer said. "I make a cognizant effort to take advantage of that."

With the Twins, an organization with which he spent his first 14 professional seasons, Cuddyer established his "Cuddies Buddies" ticket program that allowed more than 25,000 children a chance to attend a Major League game that they might not have had. He also started the Michael Cuddyer Celebrity Waiter Dinner, during which teammates served dinner to guests. From 2007 to 2011, it raised more than $160,000 for Boys and Girls Clubs.

Cuddyer has long been involved with the Cheerful Givers organization, was on the Twins Community Fund board of directors and helped secure a $250,000 grant through the Pepsi Refresh Project that was donated to the Courage Center in Minnesota.

The Roberto Clemente Award recognizes a player who best represents the game through positive contributions on and off the field, such as sportsmanship and community involvement. It was named for the Hall of Famer and 15-time All-Star who died in a plane crash on New Year's Eve 1972 while attempting to deliver supplies to earthquake victims in Nicaragua.

Rockies pondering winter ball for Chacin

SAN FRANCISCO -- Whether Rockies right-hander Jhoulys Chacin pitches in winter ball in Venezuela will depend on how he makes adjustments during the course of his final outings, and not just on building a catalogue of innings, pitching coach Bo McLaughlin said Tuesday.

Chacin (2-5, 4.58 ERA), missed more than three months with a nerve issue in his chest and has made just 11 starts, covering 55 innings. Chacin mentioned after five strong innings Monday night, when he didn't figure in the decision in a 2-1 loss to the Giants, that he will discuss winter ball with the organization.

McLaughlin said if Chacin pitches the way he did Monday, when he didn't have his best stuff but quickly found ways to keep innings form spinning out of control, he might not need the postseason work.

"The first game he came back, everything was good timing, good rhythm and make a lot of good pitches," McLaughlin said. "Then he started feeling better and better, but he got out of his delivery. But last night whenever he got out of his delivery, he made the adjustments to get back. He did it three times last night and was excellent. If he can keep on doing that, I don't know whether he needs a whole lot of [winter] innings. We'll have to see how he goes."

For now, Chacin said he plans to go to the Rockies' complex in Scottsdale, Ariz., to throw a few innings during instructional ball. If he pitches beyond that, it'll be in Venezuela for Caracas.

"I don't know if they're going to let me pitch in Venezuela," Chacin said. "I want to but I don't know if they've made a decision."

Reducing passed balls will be priority for Rosario

SAN FRANCISCO -- Catcher Wilin Rosario, whose passed ball Monday night allowed a run to score in the Rockies' 2-1 loss to the Giants, is expected to do some kind of catching work at the organization's request after the regular season ends, manager Jim Tracy said Tuesday.

Rosario, 23, who leads National League rookies with 24 home runs but also leads Major League catchers with 20 passed balls, could participate in instructional ball or winter ball in the Dominican Republic with an eye toward improving fundamentals. Tracy said it isn't clear what prescription the organization will offer, but there will be one.

"We're talking about a number of different things," Tracy said. "I really don't want to get into the details of it today, but putting a program in place for him to get started on sooner than later is something that we are gearing ourselves toward.

"Moving forward, these things have to improve measurably between now and the start of next season. Those type of things matter, as we have seen."

Rosario committed five passed balls in two one-run losses in Philadelphia earlier this month.

In the current four-game series with the Giants, Rosario will not catch Thursday, when left-handed veteran Jorge De La Rosa makes his season debut. De La Rosa, completing a comeback from Tommy John elbow surgery, will pitch to Jordan Pacheco, Tracy said.
