Randy Dobnak signed a minor league deal with the Mariners last November, and he’s spent the first 10 weeks of the season with Triple-A Tacoma. However, Ari Alexander of 7News Boston reports that the right-hander has a June 15 upward mobility clause in his contract. Presuming Dobnak triggers the clause, Seattle will have to offer him to the league’s other 29 teams. If another club wants to put him on its 40-man roster, the Mariners must either add him to their 40-man or trade him to a team that’s willing to do so. If no other teams are interested in rostering Dobnak, he will remain in Seattle’s minor league system. It’s worth noting that Dobnak still has minor league options and less than five years of major league service time, so a team that adds him to its 40-man roster could still keep him stashed at Triple-A.

They say there’s no such thing as too much pitching depth, but the 2026 Mariners might be the closest thing you’ll find to an exception. They’re currently running a six-man rotation of Bryan Woo, Logan Gilbert, George Kirby, Emerson Hancock, Bryce Miller, and Luis Castillo. They also have Cooper Criswell in their bullpen and veteran Casey Lawrence pitching alongside Dobnak in the Tacoma Rainiers rotation. While the M’s would surely like to keep Dobnak around as depth, the question is whether or not they’re willing to give up a 40-man spot to do so. They’re currently running a seven-man bullpen to accommodate their six-man rotation, and they have four players on the 10-day IL. That means space on their 40-man is at a premium.

Most teams aren’t as well-off as the Mariners in the starting pitching department, so it wouldn’t be surprising to see someone else trade for Dobnak. The 31-year-old has 39 games of MLB experience and perfectly respectable numbers at Triple-A this year. He has pitched into at least the fifth inning in all 12 of his starts, averaging 5 1/3 per outing. While his 4.50 ERA doesn’t jump off the page, it’s important to keep in mind that he’s playing in the hitter-friendly Pacific Coast League. His ERA- is 85, which is 15% better than the league average, and his 59.9% groundball rate is the highest among all qualified Triple-A pitchers.
