While facing off against Pittsburgh's Nos. 2 through 5 hitters, Garcia navigated a fairly stress-free 17-pitch frame to sew up the win. He could be in the mix for more closing opportunities in the short term, as manager Torey Lovullo told Jack Sommers of SI.com after the game that Paul Sewald -- who leads the team with 24 saves but blew two of his last three chances -- will be moved into a lower-leverage role for the time being. Rather than settling on a designated closer, Lovullo indicated he plans to play the matchups in the ninth inning, so the left-handed Garcia may be deployed primarily against left-handed-heavy portions of the lineup late in games. Lovullo mentioned Jonathan Loaisiga as another pitcher who might factor into the late-inning picture, and Juan Morillo and Kevin Ginkel could also be part of the mix.

Tuesday's matchup was mostly a pitchers' duel, as neither team scored through eight innings. Arizona finally broke out for a four-run ninth, and then turned the ball over to closer Paul Sewald. However, the veteran reliever couldn't get the job done, as he got just two outs while allowing three runs on four hits. With star rookie JJ Wetherholt coming up for the Cardinals and the tying run on first base, Arizona manager Torey Luvollo turned to Garcia to get the final out. He was able to do by striking out Wetherholt on four pitches, in the process recording the first save of his career. Garcia has been effective this season with a 2.50 ERA and 19:5 K:BB through 18 innings, but Sewald has a firm hold on the team's closer role despite his struggles Tuesday.
