--C Chris Iannetta has hit three of the Rockies' past four grand slams, dating to Sept. 16 of last season. In a span of 35 games since that date, 12 of Iannetta's 25 RBIs have been on grand slams.

--RHP Ryan Speier, who has been on the disabled list since April 19 with a strained left hamstring, pitched one scoreless inning for Class A Modesto on Wednesday, allowing one hit and one walk.

MEDICAL WATCH:

SS Troy Tulowitzki (left elbow contusion, sore left shin) left the May 13 game, and he didn't play May 14. He expects to play May 15.

INF Jeff Baker (sprained left wrist) went on the 15-day disabled list retroactive to April 27.

LHP Franklin Morales (strained left shoulder) went on the 15-day disabled list April 22. He threw a bullpen session May 9.

RHP Ryan Speier (strained left hamstring) went on the 15-day disabled list retroactive to April 19. He threw a bullpen session April 27, and he began a rehab assignment with Class A Modesto on May 13.

RHP Taylor Buchholz (partial tear in right ulnar collateral ligament) went on the 15-day disabled list retroactive to March 27, and he was transferred to the 60-day DL on April 22. He was throwing in extended spring training in early May, hoping to avoid season-ending Tommy John surgery.

LHP Jeff Francis (left shoulder surgery in February 2009) went on the 60-day disabled list April 5. He likely will miss the entire season. Recovery time ranges from six to 12 months, meaning it's possible Francis could pitch in September but not very likely.
