The Arizona Diamondbacks placed reliever Josh Collmenter on the 15-day disabled list with ulcers, AZCentral.com reported Friday.
Manager Kirk Gibson said Collmenter became ill on Thursday.
Collmenter is 3-3 with a 4.24 ERA in 22 appearances.
The Diamondbacks recalled right-hander Brad Bergesen from Class AAA Reno to take Collmenter's spot on the roster.
Bergesen was selected off waivers from the Baltimore Orioles in July. He had a 1.80 ERA in three relief appearance for Arizona before recently being optioned to Reno.
