Duffy is stretching out as a starter this spring but could also make the Rangers' Opening Day roster as a starter or reliever, Jeff Wilson of Rangerstoday.com reports.
Duffy is currently in camp as a non-roster invitee, but he is set to compete with Cody Bradford, Adrian Sampson and some of the team's prospects to earn a roster spot. He has battled arm injuries during the last two seasons and hasn't pitched in the majors since 2021, but he is currently healthy and could take advantage of the Rangers' lack of pitching depth. Duffy was with the Rangers' organization in 2023, pitching as a reliever for Double-A Frisco and Triple-A Round Rock, but he stretched out as a starter in the Puerto Rican Winter League. There, the left-hander didn't allow an earned run over 15.2 innings while striking out 19 and limiting opponents to a .161 batting average.
