RENO. Nev. -- The Diamondbacks on Wednesday promoted right-hander Aaron Blair from Double-A Mobile to Triple-A Reno and Blair will make his Triple-A debut against Tacoma.
Blair was rated as Arizona's No. 3 overall prospect by both Baseball America and MLB.com at the start of the season.
Blair, 23, went 6-3 with a 2.70 ERA in 13 starts for the BayBears this season. He allowed three earned runs or less in 12 of those outings, and he worked at least five innings in all 13 of them.
The Las Vegas native began last season at Low-A South Bend but earned promotions to Advanced-A Visalia and Mobile to close out his 2014 campaign. He finished 9-5 with a 3.56 ERA in 27 starts across the three levels.
Blair was drafted by the Diamondbacks in the first round (No. 36 overall) of the 2013 draft out of Marshall University.
In a corresponding move, Aces infielder Danny Worth was placed on the seven-day disabled list. Worth leads the Pacific Coast League in batting average (.365).
UPDATE: Blair gave up eight runs on seven hits in four innings Wednesday against Tacoma, which tagged the righty for four extra-base hits, including two home runs.
