Blackmon looking to improve in second stint

SAN DIEGO -- Rockies outfielder Charlie Blackmon has a chance to erase the struggles of his first promotion to the Rockies.

Blackmon hit .240 with one home run and two RBIs during his first stint, 12 games from May 12-29 -- a stint that ended with a 2-for-10 rut in his final six games. But Blackmon has corrected his swing since being sent back to Triple-A Colorado Springs. In his last 10 games, Blackmon hit .400 (14-for-35).

"It wasn't one thing that got me going, just a little adjustment here and there -- make sure you keep your front side in, all those basic little things that sometimes you get away from," Blackmon said. "It all came together.

"When you're here, it's a litmus test. You see how things are going and prepare yourself against some really good competition. I went down, tried to make my adjustments."

The promotion earlier this year was the first time Blackmon hasn't impressed at the big league level. He had a strong early start as a rookie in 2011, but suffered a broken foot and missed the rest of the year. Last season, injuries kept him out of the big leagues until late in the season, but he hit .283 with eight doubles in 42 games.

This could represent a chance to prove he belongs. Two outfielders called up earlier, Corey Dickerson and Tyler Colvin, are hitting .179 and .162, respectively. Blackmon didn't start Monday's game against the Padres at Petco Park, however. Dickerson was in left field in place of Carlos Gonzalez, who was nursing a sprained right middle finger. Colvin played center.

Blackmon said he doesn't know what is planned for him, but he hopes being called up in San Diego is a good omen. It's where he made his Major League debut on June 7, 2011.

"I told my dad, I'm back where it all began," Blackmon said.

CarGo misses opener, but plans to play through pain

SAN DIEGO -- Rockies outfielder Carlos Gonzalez sat out Monday night's game with the Padres after spraining his middle finger Sunday against the D-backs.

Gonzalez, the National League leader with 24 home runs, said he doesn't know when he'll return, but he knows he'll still be hurting when he does.

"I know that I'm going to have a little soreness for a little while, but I want to get to the point where I can play through it," Gonzalez said. "I don't feel good enough to play, but I'm not waiting to feel 100 percent. I want to feel good enough to go out and play for my team."

It is the second time in less than a week that Gonzalez has been injured. He suffered a back strain and missed Friday's game in Arizona. Sunday's injury occurred when he struck out in the sixth inning on a slider from D-backs lefty Patrick Corbin.

"I was walking back to the outfield and I knew that I hurt myself a little bit, then it got worse," said Gonzalez, who left the game in the ninth after fouling off a pitch from reliever Josh Collmenter.

To cover themselves in an outfield already depleted by the absence of regular center fielder Dexter Fowler, who began what figures to be a brief injury rehab assignment on Monday, the Rockies recalled outfielder Charlie Blackmon from Triple-A Colorado Springs. The Rockies made the move because they had to place right-hander Roy Oswalt on the 15-day disabled list with a strained left hamstring.
