Pearce and Thomas were designated to make room on New York’s roster for outfielder Brett Gardner and right-hander David Aardsma, who were activated from the 60-day disabled list last night.

Pearce appeared in 12 games for the Yankees after being acquired by the club from the Houston Astros. Over 25 at-bats, the 29-year-old hit .160/.300/.280 with one home run.

Thomas, 28, appeared in four games with the Yankees this season, allowing three runs over three innings of work. The southpaw spent most of the year with the club’s Triple-A affiliate, posting an ERA of 3.45 over 57 1/3 innings.
