Mets option Ike Davis, Robert Carson, and Mike Baxter to Triple-A Las Vegas

The Mets have optioned Ike Davis, Robert Carson, and Mike Baxter to Triple-A Las Vegas, quite possibly the biggest in-season shakeup of the team's roster since Sandy Alderson took over as general manager.

Davis is, of course, the biggest name of the three, as he's been with the Mets since he was recalled from the minors early in the 2010 season. For the second straight year, though, he's struggled mightily at the plate. In 207 plate appearances this year, he hit just .161/.242/.258, one of the worst slash lines in the game among regular players.

Carson surrendered his eighth home run of the season this afternoon in just eighteen innings of work. It's been pretty clear for a while that he's not fit for pitching at baseball's highest level right now.

And last but not least, Baxter had a hard time at the plate, hitting .212/.333/.282 in 102 plate appearances. The Mets will announce corresponding roster moves later today, but it wouldn't be a surprise if they finally stopped carrying six outfielders on the 25-man roster.
