Diamondbacks, Shawn Dubin Agree To Minor League Deal

The D-backs and free agent righty Shawn Dubin agreed to a minor league deal, per Baseball America’s Matt Eddy. The agreement was actually reached last month, based on Dubin’s transaction log at MLB.com, but apparently didn’t become finalized until more recently. He’s represented by Excel Sports Management.

Dubin, 30, has spent nearly his entire career in the Astros organization. Houston selected him in the 13th round of the 2018 draft, and he’s pitched in parts of each of the past three seasons with them. Dubin has posted decent results and strong strikeout rates in the upper minors, and he showed some promise with the ’24 Astros when he logged 45 1/3 innings with a 4.17 ERA and a 23.7% strikeout rate. Command has long been an issue for the righty, however, and that was the case in ’24 as well, when he issued a walk to 12.6% of his opponents.

In 2025, Dubin turned in strong Triple-A results in a small sample (one run, four hits, one walk, 14 strikeouts in 8 2/3 innings) before being summoned to the majors. He was tagged for a 5.61 ERA with a surprisingly sharp 7.2% walk rate but also a diminished 18.9% strikeout rate in 25 2/3 innings. Houston designated him for assignment in late August.

The Orioles claimed Dubin, and he pitched eight innings for them in the final few weeks of the season. He allowed only three runs in that time, but he missed time with an elbow injury. Dubin has typically sat 94-96 mph with his fastball, but his average velocity with the Orioles checked in at 93.6 mph, which stood as a clear red flag. Imaging on did not reveal any major damage, however, and Dubin told the Orioles beat in September that he expected to avoid surgery and have a normal offseason after a few weeks of downtime (via the Baltimore Banner’s Andy Kostka). Baltimore outrighted him off the roster following the season. He elected to become a minor league free agent.

Dubin has extensive experience working as both a starter and a reliever. Assuming he’s healthy and invited to major league camp this spring, he can compete for a swingman role on a D-backs staff that is generally short on innings. Re-signing Merrill Kelly gave the Snakes a veteran anchor, and he’ll join Ryne Nelson, Brandon Pfaadt, Eduardo Rodriguez and Michael Soroka in the rotation as things currently stand. Rodriguez and especially Soroka have both missed time with injuries in recent seasons, however, and the depth options beyond that top quintet are mostly lacking in major league experience.
