The club selected the contract of right-handed pitcher Marcos Mateo from Triple-A El Paso and recalled righty Kevin Quackenbush from El Paso.
After Tuesday's 3-2, 11-inning victory over the Giants, the team optioned righty Nick Vincent to El Paso, as Vincent threw 33 pitches in the game and wouldn't have been available for Wednesday's game.
The club also placed right-handed reliever Dale Thayer on the 15-day disabled list, retroactive to June 17, with a strained right shoulder.
