Henry Schulman of the San Francisco Chronicle writes that the Giants are considering significant changes to their starting lineup.
Scoreless over the past 20 innings, the offense obviously needs a significant jolt. While they await the return of Mark DeRosa, the team is reportedly mulling moving Freddy Sanchez to third base, allowing Juan Uribe to play second base. Pablo Sandoval would flip over to first base, a promising development for ongoing duel eligibility. With Sandoval at first base, Aubrey Huff would move to left field. The biggest losers here would be John Bowker and Nate Schierholtz, as they would be benched in favor of the hot-hitting Andres Torres, who would start in right field. The team could also revisit the idea of promoting Buster Posey, but they'll try to solve their offensive woes with the current 25-man roster for now. Stay tuned.
Jeremy Affeldt underwent an MRI on Monday which revealed a strain in his left hamstring.
Affeldt suffered the injury while trying to field a bunt during the eighth inning of Sunday's game. He will be reevaluated over the next few days. The Giants have an off-day on Monday, but they can ill-afford living without one of their top relievers for long. Affeldt has a 3.12 ERA over his first 17 appearances this season.
Mark DeRosa (wrist) will not be activated from the disabled list on Tuesday, the first day he is eligible.
The Giants still want DeRosa to make a few appearances down on the farm and DeRosa has yet to report to any of the club's many minor league affiliates. He has been sidelined sine May 9 with a sore left wrist and probably won't be ready for the big leagues until Thursday, Friday, or later.
Todd Wellemeyer will make his next scheduled start against the Nationals on Tuesday.
With an off-day scheduled for Monday, the Giants had considered skipping the Wellemeyer in the rotation. Still, Wellemeyer is 2-4 with a 5.71 ERA over eight games (seven starts), so he has very little margin for error. Tim Lincecum will start with an extra-day of rest on Wednesday.
