The Arizona Diamondbacks announced Sunday that they have recalled relief pitchers David Hernandez and Tony Sipp from Triple-A Reno.
Both players began the season with the big league club, but struggled over the course of the season, with Hernandez accumulating a 5.59 ERA with five blown saves (six losses) while Sipp had a 3.94 ERA with the Diamondbacks, allowing 31% of the runners he inherited to score.
General manager Kevin Towers and the Diamondbacks optioned Hernandez to Reno on August 11. While with the Aces, the 28-year-old Hernandez tallied 12 strikeouts in 9.2 innings pitched, compiling a 0.93 ERA with two saves.
Sipp, 30, was designated for assignment earlier in the season, then optioned to Reno on August 4. There, he managed to hold opponents scoreless in eight of his nine appearances, compiling a 0.90 ERA in 10.0 innings pitched while striking out 12.
Following the moves, the Diamondbacks' active roster stands at 27.
