Newly acquired Diamondbacks reliever Dominic Leone has struggled this season, going 0-4 with a 6.35 ERA in 10 relief appearances. However, Arizona is banking on him finding the form he had last season, when he went 8-2 with a 2.17 ERA in 57 relief outings for the Mariners.
"Last year, you look at his numbers and he's 8-2 with a 2.17 [ERA], and we believe that that is the pitcher that we're going to get," Arizona manager Dave Stewart said, per MLB.com.
