DENVER -- Rockies pitcher Jorge De La Rosa is still on his road to recovery from Tommy John surgery on his left elbow, which he underwent last June.
"He's not doing any throwing right now, just being treated," said Rockies manager Jim Tracy.
De La Rosa has had his rehab assignments halted twice and has not pitched in a game since May 10 of last season. His injury has been a huge blow to a starting rotation that has struggled to find its footing, as he won 16 games in 2009.

Right-hander Jhoulys Chacin is continuing to progress and is now playing catch on flat ground, Tracy said. Chacin was optioned to Triple-A Colorado Springs -- after going 0-3 with a 7.30 ERA in five starts -- before the Rockies rescinded the move and instead placed him on the 15-day disabled list with inflammation in his right shoulder. Chacin had sub-4.00 ERAs in 2010 and '11.
Right-hander Juan Nicasio, placed on the 15-day disabled list June 3, has full range of motion back in his left knee. Nicasio (2-3, 5.28 ERA) is on track to do some light tossing in a couple of days.
Catcher Ramon Hernandez currently is not participating in any baseball activity. Hernandez was added to the 15-day disabled list May 24 with a left hand strain.
Utility infielder Jonathan Herrera's hamstring is fine but he has experienced some soreness in his right shoulder. After an MRI, the Rockies determined nothing is structurally wrong with the shoulder. Herrera went on the 15-day disabled list May 22 with a strained right hamstring.
