Locastro got a start at each outfield position this season while appearing as a pinch-hitter five times and once as a pinch-runner. For what it’s worth, he had a good run, if short-lived, as he knocked four singles in eleven at-bats, stealing a pair of bases and scoring four runs. Locastro’s utility role will presumably be assumed by new arrival Blake Swihart.
Clarke was the Diamondbacks 10th ranked prospect per MLB.com, and though he’s not as heralded as fellow right-handers like Jon Duplantier and Taylor Widener, Clarke is nonetheless an intriguing arm with stellar control and a hopeful future in Arizona’s rotation. He has struggled to kick off the season for Triple-A Reno, going 1-1 with a 7.36 ERA, but he put in a solid campaign in 2018 with an overall 13-8 record and 4.03 ERA over a full season in Reno.
Clarke provides the bullpen with an extra arm while they await Swihart’s arrival from Boston. Swihart will likely join the team on Monday in Pittsburgh, per MLB.com’s Steve Gilbert (via Twitter). The former catcher will shed his shinguards in Arizona, who already have three catchers on the roster.
