The Pirates designated left-hander Mike Zagurski for assignment today and added Brandon Cumpton, today's starting pitcher, to the active and 40-man rosters.
The Pirates have 10 days to trade or release Zagurski, who was a non-roster invitee to spring training. They can send him to the minors if he clears waivers, but they would need his permission to do so.
Zagurski joined the Pirates on May 27, four days ahead of the June 1 opt-out clause in his contract. He allowed 10 runs on 10 hits and eight walks in six innings.
