Casey Lawrence

Right-hander Casey Lawrence has elected free agency after being outrighted to Triple-A Tacoma by the Mariners, according to the transactions log on his MLB.com profile page.

Lawrence, 37, was DFA’d over the weekend in what has become an extremely familiar pattern for him and the Mariners. He’s been shuttled between Tacoma and Seattle all throughout the 2025 campaign so far with multiple trips to the waiver wire in between stints, utilized effectively as a 41st member of the 40-man roster who can be called upon when the Mariners need an extra arm before being cut loose and placed on waivers once he’s provided some length out of the bullpen.

It’s an unusual role, but he’s done fairly well in it this year. Lawrence has a 4.08 ERA and 4.09 FIP across 17 2/3 innings of work, almost all of which came as a member of the Mariners save one short stint with the Blue Jays where he allowed three runs on six hits in 2 2/3 innings of long relief work. The arrangement has allowed Lawrence to find his first big league opportunities since 2023, when he struggled to a 6.59 ERA in 27 innings of work for the Cardinals out of the bullpen.

That was the only time in his career he donned a major league uniform other than those of the Blue Jays and Mariners, but his 96 2/3 innings in the majors prior to that time in St. Louis were largely more of the same as he pitched to a 6.80 ERA and 5.31 FIP in 44 appearances between 2017 and 2022. A stint with Nippon Professional Baseball’s Hiroshima Carp in 2019 wasn’t especially fruitful either, as he allowed six runs in five innings during his lone Central League appearance and mostly posted middling numbers for the Carp’s Western League team, the NPB equivalent of a minor league club.

While Lawrence’s results have improved substantially this year, it’s anyone’s guess whether that league average production is sustainable for the right-hander. His 8.8% strikeout rate is nothing short of microscopic, but he’s walked just 1.3% of his opponents and has a fairly solid 40.8% ground ball rate. If anything Lawrence’s .348 BABIP and 51.6% strand rate suggest he may be getting slightly unlucky when it comes to batted ball luck and sequencing, although an 8.0% home run to fly ball ratio seems unlikely to be sustainable. Lawrence’s 4.54 SIERA paints him as an average to slightly below average pitcher overall this year, and given Lawrence’s status as the team’s extra arm over the first few months of the season the Mariners are likely to be quite satisfied with that level of production.

Lawrence is now a free agent and able to sign with any of the league’s 30 clubs, though it wouldn’t be a surprise if he finds himself re-signing with the Mariners on a fresh minor league deal within the next few days to restart the cycle between Triple-A and the majors Seattle brass seem content to continue pushing him through. It’s an unequivocal win for Lawrence, who collects big league service time and salary even when he’s in DFA limbo or on the waiver wire. That means this process has allowed him to collect a healthy portion of the league minimum salary to this point in the season and more than a month of big league service time.

The Mariners announced Friday that right-hander Casey Lawrence again passed through waivers following a recent DFA. He’s been assigned outright to Triple-A Tacoma.

Lawrence has the right to reject the assignment and elect free agency, although at this point, whether he chooses to do so seemingly has little bearing on his future with the organization. Lawrence has been designated for assignment by Seattle a whopping four times in the past six weeks — plus another time by the Blue Jays, who briefly claimed him from Seattle. (He elected free agency following that DFA and re-signed with the Mariners.) Each time, he’s returned to the Mariners.

In 2025 alone, Lawrence has had four stints with the Mariners, and there’s little reason to think it’ll stop there. He appears perfectly content to function as an effective 41st player on the 40-man roster, being selected to the roster whenever the big league club needs some extra length in the bullpen and then quickly being placed on waivers. The 37-year-old righty clearly has a good relationship with the organization and is comfortable in the Tacoma area, which is no surprise given that he also spent the entire 2024 season pitching for the Mariners’ Triple-A squad there.

Lawrence has pitched in six MLB games this year — five with Seattle, one with Toronto — and eaten up 17 2/3 innings in a long relief role. He’s logged a 4.08 ERA in that time, including a flat 3.00 mark in his 15 frames as a Mariner. He’s averaging just 88 mph on his fastball and carries a minuscule 8.8% strikeout rate, but Lawrence has also walked only one of the 80 men he’s faced (1.3%).

It’s not the smoothest way to earn a living, but by my count he’s picked up 23 days of major league service time this year. Even with a league-minimum split on the contracts he’s signing — and the Mariners are presumably compensating him a bit better than that — he’d have already earned a bit more than $96K in just big league salary, before factoring in any minor league pay. Assuming he has several more stints of this nature ahead of him, he’ll take home a fair bit more cash in 2025 than your standard mid-30s journeyman on the fringes of big league rosters, however unorthodox the road to that endgame may be.

Right-hander Casey Lawrence is back with the Mariners — again. The two sides have agreed to yet another minor league pact, per the Mariners’ transaction log at MLB.com. Lawrence is represented by Big League Management.

If and when the 37-year-old veteran makes his way back to the major league roster, it’ll be his fourth stint with Seattle in 2025 alone. It’s been a wild year for Lawrence, who re-signed with the Mariners as a minor league free agent over the winter. This is the third season in which he’s logged big league time with the M’s, though his prior stints haven’t involved such frequent rides on the DFA carousel.

Lawrence was claimed by the Blue Jays on the heels of his most recent Mariners DFA, also marking the third season in which he’s suited up for Toronto. The Jays designated him after one long relief outing (2 2/3 innings, three runs allowed). He elected free agency after passing through waivers and is now back in the Pacific Northwest.

Across his three stints with Seattle this season, Lawrence has pitched 10 innings and allowed four earned runs (3.60 ERA) on 14 hits and a walk with four strikeouts. Coupled with his lone appearance in Toronto, Lawrence has a 4.97 ERA on the season. He’s fanned just 8.3% of the hitters he’s faced but also has just a 1.7% walk rate. He’s also made a pair of starts with the Mariners’ Triple-A affiliate, totaling 10 1/3 innings and holding opponents to five runs on 13 hits with an 8-to-3 K/BB ratio (18.2 K%, 6.8 BB%).

Lawrence spent the entire 2024 season in the rotation for the Mariners’ Tacoma affiliate as well, so despite the frequent DFAs — four times already in a six-week-old season — there’s probably some stability with regard to his living situation. It may seem inconvenient to the player or even callous on the surface, but Lawrence seems comfortable with an arrangement that effectively renders him the 41st man on Seattle’s 40-man roster. Teams and players are typically up-front with one another in situations like this one; it’s not as though Lawrence is being blindsided by the frequent removal from the roster. The Mariners will likely continue to shuttle him on and off the 40-man roster when they need length in the bullpen or a spot start.
