The New York Yankees have designated reliever David Carpenter for assignment and have activated Masahiro Tanaka.
Carpenter, 29, has struggled this season giving up 10 earned runs in 18 2/3 innings. The Yankees expected much more out of him when they traded former top prospect Manny Banuelos to the Braves for Carpenter. The righty was dominant in his two years in Atlanta and we could see a reunion, as the Braves bullpen continues to struggle.
