Rockies delaying decision on DL for Dickerson

LOS ANGELES -- Manager Walt Weiss said the Rockies are worried about the left foot of left fielder Corey Dickerson, who left Saturday night's game after his latest flare-up of plantar fasciitis.

Dickerson felt pain when he abruptly tried to stop while chasing a deep fly ball in Saturday's 7-1 victory. The problem first appeared late in Spring Training, and has cost him several starts and limited him to shortened appearances over the last 10 games.

"It's a concern because he's been dealing with it for a long time and he's a little more sore than he's been," Weiss said.

Asked if the disabled list is a possibility, Weiss said, "Yeah, not today, not a move we're going to do now. We're going to see how it plays out the next couple of days. It is concerning because we know the nature of that injury. It's a tough injury. It doesn't go away."

The issue is essentially tissue damage in the heel area. While many treatment options exist for most folks to return to a pain-free life, little, short of surgery, can end the pain from the impact of playing a Major League game, with abrupt changes of running from dirt to grass, and the pushing and landing that comes with play. So most players try to manage until it prevents them from doing their jobs.

Dickerson, hitting .312 with five home runs and 16 RBIs, said he didn't know if a trip to the DL would be enough to help, since "it will take a lot of time, or tearing [of tissue], to get better."

Dickerson has been committed to playing in pain. "Yesterday was the best it has ever felt, and I was running well," he said.

Worth noting:

• Lefty pitcher Jorge De La Rosa did light jogging and stretching Sunday morning, a day after leaving Saturday's game after 7 1/3 scoreless innings with left groin pain. Whether he makes his next start is dependent on how he feels during and after his throwing sessions in the coming days, Weiss said.

• Shortstop Troy Tulowitzki said he felt good during change-of-direction agility drills Sunday morning -- two days after leaving a game with left quadriceps tightness. Weiss said he was available Sunday for an at-bat late, and a start Monday at home against the Phillies is possible.

• Righty reliever Brooks Brown, placed on the 15-day disabled list Thursday (retroactive to May 4), struck out two while pitching one inning for Triple-A Albuquerque on a rehab assignment Saturday. He is eligible to return Tuesday.

• An interesting pregame drill involved first baseman Wilin Rosario fielding balls hit by third-base coach Stu Cole while wearing a small fielder's glove, befitting a middle infielder. But don't worry. The Rockies are looking at Rosario, a catcher who moved to first base when Nick Hundley signed, to supplant Tulowitzki or second baseman DJ LeMahieu.

"It teaches me to field with both hands, and to use my legs, like a shortstop," said Rosario, who finished by taking grounders with his first baseman's mitt.
