Outfielder Chris Carter is now playing with the Seibu Lions, reports ESPN New York's Adam Rubin (on Twitter). This is the Chris Carter who was traded from the Red Sox to the Mets for Billy Wagner in 2009, not the current Athletics prospect.
Carter, 29, has hit .263/.316/.374 with four homers in 206 big league plate appearances spread across three seasons. He spent last year in Triple-A with the Rays and Braves, hitting .286/.331/.488 with 14 homers in 308 plate appearances. The left-handed swinger has experience at both corner outfield spots as well as first base.
