UPDATE (FRIDAY) - The Marlins officially announced the deal, and it is in fact a major-league deal for McGehee. To make room on the 25-man roster, Miami placed Jeff Baker on the 15-day disabled list with a left intercostal strain.
ORIGINAL (THURSDAY) - The Marlins are expected to bring back third baseman Casey McGehee on what appears to be a major-league deal, as first reported by Andy Slater of 940AM WINZ in Miami. A baseball source told SB Nation that McGehee has not yet signed with anyone because he is on release waivers until Friday afternoon, though multiple outlets have reported that McGehee will join the Marlins as soon as he clears waivers.
McGehee, 32, returns to Miami after only a few months as a member of the Giants, who acquired him from the Marlins in exchange for prospects Luis Castillo and Kendry Flores in late December. He hit just .213/.275/.299 with two home runs in 49 games with San Francisco before ultimately losing his job to Matt Duffy and being designated for assignment.
McGehee had a breakout year in 2014 with Miami, hitting .287 with four homers and 76 RBI in 160 games after spending 2013 in Japan. He will likely split time with rookie Derek Dietrich at the hot corner, and also has the ability to play first base and pinch-hit for the Marlins.
