Buchanan was designated for assignment by the Cubs on Monday.

EDGE Analysis

The move was made to make room on the roster for Zac Rosscup, who had his contract purchased earlier Monday. Buchanan had a 4.75 ERA and 29:19 K:BB through 41.2 innings (eight starts) with Triple-A Iowa before being ousted from the Cubs' 40-man. He's got some major-league experience under his belt, so he could draw some interest on waivers, otherwise he'll likely report back to Iowa.
