PITTSBURGH — The Pittsburgh Pirates continue making roster moves to give themselves the best chance to win.The Pirates recalled three players from Triple-A Indianapolis, pitchers in right-hander Noah Murdock and left-hander Hunter Barco and outfielder Jhostynxon Garcia, ahead of their series finale vs. the Arizona Diamondbacks at PNC Park on July 29.Pittsburgh also made three corresponding moves to make room on the 26-man roster, as they optioned pitchers in left-hander Brandon Eisert and right-hander Isaac Mattson, plus utility man Tyler Callihan.The Pirates needed pitchers after long bullpen outings vs. the Diamondbacks, including 4.2 innings in the 3-2 walk-off win in 10 innings on July 27 and then eight innings in the comeback, but ultimately 8-7 defeat in 12 innings.Barco and Murdock provide the Pirates available arms, as they are in the midst of 17 games in 17 days and will make similar moves like this during this time, especially if they have long bullpen games.Garcia comes back, as Callihan has struggled for the Pirates, slashing .161/.197/.274 for an OPS of .471 in his past 25 games.The Pirates hope they can get the right-handed power bat they need from Garcia, as they have struggled against left-handed pitching this season.Make sure to visit Pirates OnSI for the latest news, updates, interviews and insight on the Pittsburgh Pirates!Add us as a preferred source on GoogleFollow
