D-backs place Collmenter on DL

The Arizona Diamondbacks placed right-hander Josh Collmenter on

the 15-day disabled list on Friday with ulcers.

Collmenter started the season in the rotation but demoted to the

bullpen after four rocky starts. He returned to the rotation to

make five starts and has posted a 3-1 record and a 2.41 ERA in his

last 18 appearances. Collmenter is 3-3 overall with a 4.24 ERA in

22 games.

The Diamondbacks recalled right-hander Brad Bergesen from

Triple-A Reno. Bergesen posted a 1.80 ERA in five innings across

three relief appearances in his previous stint with Arizona this

season.

Bergesen had been claimed by the Diamondbacks on July 20 from

Baltimore.
