Arizona Diamondbacks relief pitcher Luis Frias has been recalled from Triple-A Reno. Keynan Middleton (toe) landed on the injured list so Frias was brought up in a corresponding move. The 24-year-old righty really struggled earlier this year, posting a 12.34 ERA in just 11 2/3 innings out of the D-Backs bullpen so there's little to no fantasy impact here.
