SUNDAY: Arizona has officially selected Buchholz’s contract. To create space for him, the team transferred righty Randall Delgado to the 60-day DL with a strained left oblique and optioned fellow righty Jimmie Sherfy to Triple-A.

FRIDAY: The Diamondbacks will select the contract of veteran righty Clay Buchholz, manager Torey Lovullo told reporters including Nick Piecoro of the Arizona Republic (Twitter link). He’ll make a start on Sunday, so presumably the roster move won’t be made official until then.

Buchholz joined the Arizona organization earlier this month after opting out of his deal with the Royals. It turned out that the Snakes needed the extra arm. With Robbie Ray on the shelf and Taijuan Walker down for the year, the club has already dipped into its system to plug in Matt Koch. The fifth spot is open to whoever can lay claim to it; fellow veteran Kris Medlen stumbled in his attempt but is among the other pitchers still on hand at Triple-A.

Like current D-Backs GM Mike Hazen, Buchholz has spent the bulk of his career with the Red Sox organization. Now 33, Buchholz was seen as an interesting bounceback candidate by the Phillies in 2017. But he was knocked around in two starts before going down with a flexor tear.

This upcoming appearance, then, will be Buchholz’s first in the majors in over a year. In five outings in the upper minors, he has worked to a 2.93 ERA with 19 strikeouts and a dozen walks over 27 2/3 innings. The Diamondbacks would obviously be thrilled if he can provide some useful innings.
