The Seattle Mariners have signed right-handed pitcher Dane Dunning to a minor league contract, providing the 31-year-old veteran a chance to revive his career after a challenging 2023 season. While Dunning's major league numbers last year were underwhelming, his Triple-A performance showed promise, raising questions about whether he can regain his previous form and become a valuable depth piece for the Mariners.

Why it matters

The Mariners' rotation depth beyond their top five starters is thin, with young and unproven options like Logan Evans and Emerson Hancock next in line. Dunning's addition provides the team with an experienced arm who, if he can rediscover his control and ability to limit hard contact, could potentially fill a role as a long reliever or spot starter.

The details

Dunning, a former first-round draft pick, struggled in the majors last season, posting a nearly 7.00 ERA over 20 2/3 innings with the Braves and Rangers. However, his Triple-A numbers as a starter were more promising, with a 4.67 ERA, a league-average 21.6% strikeout rate, and a 7.6% walk rate across 69 1/3 innings. The Mariners are likely to use Dunning as rotational depth at Triple-A Tacoma, with his chances of cracking the Opening Day roster slim barring a string of Spring Training injuries.

  • Dunning signed his minor league contract with the Mariners on April 10, 2026.
  • In the 2023 season, Dunning made 12 major league appearances, split between the Braves and Rangers.

What’s next

Dunning will likely compete for a spot in the Mariners' rotation or bullpen during Spring Training, with his chances of making the Opening Day roster depending on how he performs and any potential injuries to the team's pitching staff.

The takeaway

The Mariners are taking a low-risk gamble on Dunning, who has shown promise in the past but has struggled with consistency in recent years. If he can regain his control and ability to limit hard contact, he could potentially provide valuable depth for a Mariners rotation that lacks proven options beyond their top five starters.
