Mariners Designate Casey Lawrence For Assignment

The Mariners announced Monday that right-hander Casey Lawrence has been designated for assignment. His spot on the roster will go to righty Troy Taylor, who’s being reinstated from the 15-day injured list. It’s also worth noting that right-hander Jesse Hahn, whom Seattle outrighted to Triple-A over the weekend, has rejected that assignment in favor of free agency, according to the transaction log at MiLB.com.

Lawrence, 37, was called to the big leagues last week for a return stint with Seattle. He pitched the final three innings of their April 9 game against the Astros and was credited with a win after allowing a pair of runs on four hits and a walk (no strikeouts). It’s the third season in which the well-traveled Lawrence has suited up for the Mariners. He also pitched with Seattle in 2017 and 2018, in addition to spending the entire 2024 season with their Triple-A club. In 127 big league innings, Lawrence has a 6.73 ERA with a 16.6% strikeout rate and 8.5% walk rate.

The Mariners clearly like Lawrence and have a good relationship with him. Since 2017, they’ve claimed him off waivers and signed him to three minor league contracts. He can be placed on waivers or traded at any point in the next five days. Waivers would be another 48-hour process.

Within a week’s time, we’ll know the outcome of his DFA, although given his track record and history with the organization, it wouldn’t be a surprise if he accepted an outright assignment or quickly re-signed on a new minor league deal after clearing waivers and electing free agency. He’s already spent the past year-plus living and pitching in the Seattle/Tacoma area, after all, and he could be called upon in similar situations if the Mariners decide they need a fresh arm in the ’pen once again.

Taylor, 23, was a quick-to-the-majors reliever who impressed during his 2024 MLB debut. A 12th-round pick by the M’s in 2022, Taylor logged 19 1/3 innings last year and turned in a 3.72 ERA with a huge 30.9% strikeout rate against a solid 8.6% walk rate. That performance came on the heels of 42 2/3 minor league innings during which the UC-Irvine product recorded a stellar 1.27 ERA with a 27.6% strikeout rate and identical 8.6% walk rate.

Taylor missed the first two-plus weeks of the season with a minor lat strain. He made five rehab appearances and was torched for six runs on nine hits (one homer) and a walk in 3 1/3 innings. Most of that damage came in one outing where he was tagged for three runs without recording an out, however. Clearly, the Mariners are encouraged by the current state of his stuff and his previously ailing lat, as they could’ve simply optioned Taylor to Triple-A rather than reinstate him to the big league roster.

Hahn, 35, pitched in the majors for the first time since 2021 earlier this year when he tossed four frames for the Mariners. Injuries have continually plagued the right-hander, who’s been limited to 29 1/3 MLB frames (and 85 innings overall) since 2019. He’s continued grinding through rehab after rehab, however, and was rewarded with a brief big league return. Hahn could get another look with the M’s on a new minor league deal or latch on elsewhere as a minor league depth option now that he’s once again a free agent.
