Don't call it a comeback. He's been here for years.
According to the Hartford Courant (and, obviously, his Twitter account), Adam Greenberg is back in professional baseball. This time, however, it's not back to the bigs for "one at bat"…it's back to Bridgeport.
Greenberg hit .255 with 126 stolen bases spread across parts of four seasons (2008-2011) with the Bridgeport Bluefish. After getting an at bat last season with the Miami Marlins, he spent Spring Training 2013 with the Baltimore Orioles.
