Marcus Thames and Matt Treanor became free agents today, according to MLB.com's Jason Beck. Both former Tigers were non-tender candidates anyway, but apparently they've been outrighted or released.
Thames, 33 in March, hit .252/.323/.453 in 294 plate appearances while playing 125 innings in left field and spending the rest of his time at DH. Thames has played a little first base and right field in his career as well.
Treanor, 34 in March, had only 14 plate appearances this year due to a hip injury. He caught 524 innings for the Marlins back in '08, earning him a $750K contract with the Tigers in December.
