The Diamondbacks recalled Hughes from Triple-A Reno on Wednesday. He'll serve as Arizona's opening pitcher for the team's series finale in Los Angeles versus the Dodgers, Jesse Friedman of GoPHNX.com reports.
Hughes allowed four earned runs in 2.2 innings during his first stint with Arizona earlier this month, but he's thrown five innings of one-run ball since returning to Triple-A. The 28-year-old lefty is likely to only pitch an inning or two Wednesday before giving way to Ryne Nelson, who is expected to pitch the bulk of innings out of the bullpen.
