ATLANTA -- After the Rockies suffered a painful 1-0 loss to the Braves on Wednesday night, manager Jim Tracy received good news when he returned to his office after the game ended.
Jorge De La Rosa, who is recovering from Tommy John surgery last June, threw three shutout innings Wednesday for Rookie-level Grand Junction. He allowed three hits and struck out five. De La Rosa threw 49 pitches, and Tracy said the left-hander's fastball sat at 91 mph and touched 94 mph.
"That was really encouraging news last night after a very tough loss," Tracy said.
Meanwhile, Troy Tulowitzki played five innings in a rehab assignment at Double-A Tulsa on Wednesday. Tulowitzki went 1-for-3 and started a double play in Tulsa's 8-6 loss to Springfield in the first game of the Texas League playoffs.
The shortstop has been on the disabled list since May 30 with a strained left groin that eventually required surgery to remove scar tissue.
Tulowitzki will play seven innings at shortstop Thursday night with Tulsa. Where he and De La Rosa go next has yet to be determined and will depend on how the Rockies' Minor League affiliates perform in the postseason. All three clubs that made the playoffs lost Wednesday night and are on the brink of elimination.
Rutledge debuts at second base in finale
ATLANTA -- Josh Rutledge made his first career start at second base Thursday for the Rockies. Rutledge has played 46 games at shortstop since Troy Tulowitzki was hurt at the end of May, but the Rockies plan to make him the everyday second baseman when Tulowitzki returns.
Rutledge has been a shortstop throughout his college and professional career, but he played 28 games at second base with Double-A Tulsa this year. Lately, he has been working with third-base coach Rich Dauer to get more comfortable at second.
"I'd like to play him at second base and see what this looks like and where it has the potential of going," manager Jim Tracy said.
Tracy said he's not sure if Rutledge will become the club's regular second baseman or if he will continue to play some shortstop until Tulowitzki returns. But he wants to start seeing Rutledge play second base so the Rockies have a point of reference to begin to evaluate where he can play going forward.
Rutledge is hitting .329 with seven home runs in 46 games since being called up from Tulsa on July 13. He has made 10 errors, including a costly throwing error that allowed the Braves to score their only run in Wednesday night's 1-0 victory.
As Rutledge gets more playing time at second base, Tracy said D.J. LeMahieu, who has been the Rockies' second baseman, will get more work at shortstop and third base.
"I want to know how versatile is this player," Tracy said. "That's what I want to know about LeMahieu."
Giambi honored to have shared field with Chipper
ATLANTA -- With Braves third baseman Chipper Jones out of the lineup Thursday, the future Hall of Famer has likely played his final game against the Rockies. In 124 games against Colorado in his career, Jones hit .323 with 31 home runs and a .607 slugging percentage.
Jones, who announced in Spring Training he would retire at the end of the season, is one of just eight players in the National League who are at least 40 years old. The slugger hasn't slowed down this season, however, hitting .304 with 14 home runs in 91 games.
At 41, Rockies first baseman Jason Giambi is one of the few players older than Jones.
Giambi said he's gotten to know Jones during his 18-year career and has been thrilled to see him have such a successful sendoff.
"I'm ecstatic for him," Giambi said. "That's the way you want to go out. What an incredible last year that he's had. It's been fun to watch him go about his business. It's been a tremendous honor to play on the same field with him."
