Rockies 6, Cardinals 2: Jorge De La Rosa carries the load to snap a three-game losing streak.

st. louis» Kyle Parker believes he’s major-league ready. Now he gets a chance to prove it.

The Rockies called up the outfielder/first baseman from Triple-A Albuquerque on Saturday to take the place of left fielder Corey Dickerson, who was placed on the disabled list with fractured ribs.

“I feel like my game still needs to improve, but I keep getting better. I have been playing a lot more first, and I feel a lot more comfortable there,” said Parker, who played 18 games for the Rockies last season but got limited at-bats and limited results. He hit .192 (5-for-26) with one run, one double and one RBI.

Parker, 25, was the 26th overall selection in the 2010 draft. In 93 games with Albuquerque this season, he hit .280, with 53 runs, 19 doubles, four triples, nine homers and 58 RBIs. After a sluggish April, he caught fire. Since May 1, he hit .315 with seven home runs, 16 doubles and a .352 on-base percentage.

The former Clemson quarterback has tried to learn to deal with the frustration of playing the waiting game in the minor leagues.

“It’s been difficult. To say it hasn’t been difficult would be a lie,” he said. “You never want to get caught in a bad mind-set, especially during the season.”

Right-hander Kyle Kendrick was placed on the 15-day DL with right shoulder inflammation. He’s scheduled to undergo an MRI on Monday.

To bolster an overtaxed bullpen, the Rockies moved righthander Christian Bergman off the DL and recalled right-hander Scott Oberg from Triple-A. The Rockies designated lefty Aaron Laffey for assignment.

DJ LeMahieu batted .400 in July. He also batted .406 in April. That makes the second baseman the first Rockie to hit .400 or better in two months of a season since Larry Walker did it in 2002, when he hit .410 in June and .438 in July.
