"It's very disappointing," Francis said before the Rockies' opener of a four-game set with the Giants. The Colorado Rockies have put left-hander Jeff Francis on the 15-day disabled list with a strained left groin and designated infielder Reid Brignac for assignment. After quelling concerns about his effectiveness with six sterling innings of one-run ball against the Cubs on Tuesday, veteran lefty Jeff Francis went on the disabled list Thursday with a left groin strain. Francis incurred the injury early in the game, but after the length of the outing, he and the club were optimistic that he might be able to stay on track for his next start Sunday. He hit .297 with two homers and 22 RBIs in 81 games for the Rockies last year. To put an outing like that together was very rewarding, because you've done the work and the preparation to go there and pitch like that, so to have that taken away is very frustrating."
