The Arizona Diamondbacks have selected right-hander pitcher Matt Stites from Triple-A Reno, optioned outfielder Tony Campana and transferred right-hander Daniel Hudson to the 60-day disabled list.
The 24-year-old Stites is making his majors debut after going 0-1 with 15 saves and a 2.89 ERA in 29 games between Double-A Mobile and Reno this season. He didn't allow an earned run in his first 11 appearances — a span of 10 2-3 innings — and converted all 12 of his save opportunities since being promoted to Reno on May 6.
Campana hit .150 in 26 games with Arizona and had his first career walk-off hit with a single in Wednesday night's 4-3 win over Milwaukee.
Hudson had Tommy John surgery for the second time in 2013.
