The Padres acquired Eric Patterson from the Red Sox, according to Jon Paul Morosi of FOX Sports (on Twitter). He is the player to be named in the Adrian Gonzalez deal, according to Dan Hayes of the North County Times (on Twitter). The Red Sox acquired Patterson from the A's for Fabian Williamson this summer.
Patterson, 27, has played second base, left field and center field in his four-year major league career. Given the Padres' outfield depth and need for a second baseman, it seems likely that they've acquiRed Patterson for infield depth. In 204 plate appearances for the A's and Red Sox last year, Patterson hit .214/.272/.406 with 11 stolen bases in 12 attempts.
