Renteria, 34, has endured a star-crossed season. When fit, he has been productive, as his .316 batting average reflects. But after spending his offseason recovering from right elbow surgery and discomfort in both shoulders, he missed two games in late April with an ailing left shoulder.
Renteria's groin ailment forced him to miss four games in a row before he tried playing in Thursday's series finale at Florida. Renteria lasted only two innings, portending his move to the DL. Since that also prevented the Giants from backdating Renteria's DL assignment, he'll be sidelined for the entire 15-day period.
"Nobody wants to go there," said a subdued Renteria -- who, interestingly enough, could be ready to rejoin the Giants at about the same time second baseman Freddy Sanchez completes his injury rehabilitation assignment.
Velez began the season with a 7-for-17 binge, which preceded a 1-for-27 skid. That hastened Andres Torres' emergence as the Giants' top multipurpose reserve outfielder, which in turn prompted Velez's demotion.
"In fairness to him, it was a small sample size with his playing time," Giants manager Bruce Bochy said of Velez. "But when [Aaron Rowand] went down and he assumed the leadoff role, he struggled there and I think he started pressing a little bit. Enough time has gone by without him getting some playing time, so we felt the best thing is let him go to Fresno and get his three or four at-bats every day."
Bochy added that Matt Downs' strong performance at second base made it easier to part with Velez, who also plays that spot.
Rohlinger, batting .333 with a .442 on-base percentage and a .506 slugging percentage at Fresno, likely will fill in at shortstop or third base as needed. He could prove particularly useful at shortstop if Juan Uribe's throwing arm, which bothered him earlier this season, flares up again.
Bautista, who pitched for Baltimore, Kansas City, Colorado, Detroit and Pittsburgh in parts of the previous six seasons, was 1-1 with a 2.19 ERA and six saves in 11 appearances for Fresno. He had 15 strikeouts and three walks in 12 1/3 innings.
"He's been the best pitcher down there," Bochy said.
