THURSDAY, 2:25pm: The Marlins have had internal discussions about third base options, but never discussed possible deals with the Giants, according to Danny Knobler of CBS Sports.com.
WEDNESDAY, 3:59pm: DeRosa is headed to the DL, according to Andrew Baggarly of the San Jose Mercury News (on Twitter). Though the repaired tendon in his wrist is fine, the area around it is inflamed. If the Marlins are going to make a run at DeRosa, it probably won't happen for a few weeks at least.
12:44pm: The Marlins "have begun weighing the merits of making a run at" Giants infielder Mark DeRosa, reports Juan C. Rodriguez of the South Florida Sun-Sentinel. DeRosa could be a solution for the Fish at third base for the remainder of the season, after which his contract is up.
DeRosa, 36, is hitting well in a small 20 plate appearance sample this season. With a crowded outfield and no openings at second base or the infield corners, the Giants may consider DeRosa expendable. Not only could they get a useful player back, but they could also clear a portion of DeRosa's $6MM salary. An extra $2-3MM would be helpful to the Giants, who may have limited payroll flexibility in the 2011-12 offseason unless they move some salary.
The Marlins considered giving the third base job to top prospect Matt Dominguez out of Spring Training, but instead sent him to Triple-A on March 24th. Eight days later Dominguez fractured his elbow. As a whole, Greg Dobbs, Donnie Murphy, Emilio Bonifacio, and Wes Helms are hitting .286/.353/.416 on the season while manning third base for the Marlins.
