PITTSBURGH — The Pittsburgh Pirates reacquired utilityman Matt Kata on Sunday in a minor league deal with the Colorado Rockies and signed right-hander Jason Davis to be a starting pitcher at Triple-A Indianapolis.

Colorado will receive future considerations for Kata, who hit .250 with one homer and 10 RBIs in 47 games with Pittsburgh last season after beginning the year with Texas. He was designated for assignment by the Pirates in October and claimed by the Rockies.

Davis is 20-22 over six major league seasons, mostly with the Indians. He was 2-0 with a 6.31 ERA in 16 games with Seattle last season after having a 4.76 ERA in eight games with Cleveland. He was in the Rangers' camp this spring but did not make the team.

Neither player was added to the Pirates' 40-man roster.
