Billy Buckner made back-to-back relief appearances during his two-day major league stay. After earning the win in Friday's extra-inning contest, Buckner allowed two homers in Saturday's loss.
The Diamondbacks needed to infuse a weary bullpen with another fresh arm. That bullpen has pitched a total of 24.1 innings over the past five days, which includes three consecutive extra-inning contests. The solution was to bring up Sidewinders closer and changeup specialist Leo Rosales up and send the worn Buckner back down to Tucson.Whether this represents a temporary or permanent solution remains to be seen. Rosales allowed six base runners in less than two innings in his major league debut Sunday. His fastball ranged from 89-91 MPH, his slider between 83-84, and his excellent changeup sat between 78-80. In Triple-A Tucson, Rosales went 9-for-9 in save opportunities and posted a 4.08 ERA in 35.1 innings.
Rosales was acquired last August for outfielder Scott Hairston last July. He had injured his pitching hand punching a wall after a blown save while he was in the Padres organization, and so did not pitch for the Diamondbacks until this season.
