Sean Sullivan pitched decently in a no-decision against the Diamondbacks on Thursday afternoon, surrendering two runs on three hits across three frames.

The 23-year-old southpaw did not walk a batter or record a strikeout in the contest. The Diamondbacks jumped him right out of the gate in this one as Jordan Lawlar smacked a leadoff single and Tim Tawa followed with a two-run homer. He then settled in and allowed just one hit while recording nine outs from there. For the spring, Sullivan holds a solid 3.86 ERA, 1.18 WHIP and a 7/3 K/BB ratio over 9 2/3 innings during Cactus League play. Given their lack of staring pitching depth, we could see him debut with the Rockies at some point in 2026.
