Rockies all-star left fielder Carlos Gonzalez struggling with a painful sprained middle finger on his right hand was placed on the 15-day disabled list Wednesday. "This is very frustrating and it's not something I wanted" Gonzalez said. "But this is something we had to do for the good of the team — and hopefully to help me get better. I mean I wanted to play but I can't be in this situation." Gonzalez has been hampered by the finger injury on his glove hand since a July 7 game at Arizona. He hoped to avoid the DL even changing his grip on the bat but he consistently reinjured the finger when he took hard swings. Rockies trainer Keith Dugger said Gonzalez has a sprain of the collateral ligament of his middle finger. "Once you injure it it can take four to six weeks to heal completely" Dugger said. "CarGo was aggravating the finger when he swung the bat. Hopefully this rest will help. Actually I know it will help some. We'll see how much." Gonzalez said he knew he was destined for the DL on Tuesday when he was unable to answer the call as a pinch hitter in the ninth inning of the Mets' 3-2 victory over the Rockies at Citi Field. Gonzalez's DL stint will be retroactive to Monday. To fill the roster slot the Rockies recalled left-handed pitcher Jeff Francis from Triple-A Colorado Springs. Francis will work out of the bullpen.
