NEW YORK -- The D-backs added Clay Buchholz to their roster Sunday so the right-hander could start against the Mets.
To make room for the veteran right-hander, the D-backs optioned reliever Jimmie Sherfy to Triple-A Reno, and they opened up a spot on their 40-man roster for Buchholz by transferring Randall Delgado from the 10-day to the 60-day disabled list.
Sherfy's performance did not warrant a demotion. The right-hander was unscored upon in three appearances since his recall from Reno and he has not allowed a run in 12 2/3 big league innings dating back to last year.
