With rosters expanding from 26 to 28 today, the Mariners announced that they have selected catcher Harry Ford and right-hander Luke Jackson. They also recalled infielder Leo Rivas. In corresponding moves, they designated right-hander Sauryn Lao for assignment and released infielder Donovan Solano.

Ford, 22, is widely considered one of the top catching prospects — and top 100 overall prospects — in the industry. The former first-rounder has spent the whole season in Triple-A Tacoma, where he’s done nothing to dissuade that line of thinking. In his first 97 games and 458 plate appearances at the Triple-A level, Ford has turned in a terrific .283/.408/.460 batting line (125 wRC+). He’s homered 16 times, swiped seven bags and walked nearly as often (16.2%) as he’s struck out (19.2%).

There are natural questions about Ford’s long-term fit on a roster that also includes 2025 AL MVP candidate Cal Raleigh. The Mariners’ franchise catcher signed a six-year extension last offseason and has obviously substantially elevated his profile since putting pen to paper on that contract. The M’s could roster both catchers and rotate them between the catching and designated hitter spot. Having two catchers with that type of offensive potential would be a clear advantage, though there’ll likely be plenty of offseason attempts to pry Ford from the Mariners’ grasp. Seattle president of baseball operations Jerry Dipoto is never one to shy away from bold trades, so he’ll presumably at least consider dealing from strength, if it addresses other areas of need.

For the time being, however, Ford will get his feet wet and bolster the Mariners’ catching depth while they chase down what looks like a very, very likely playoff berth. The Mariners currently trail the Astros by two games in the American League West but have a 2.5-game lead over the Rangers for the final Wild Card spot. Both the Houston and Texas rosters have recently been hit with several key injuries, while Seattle has remained generally healthy and also added some key lineup upgrades at the July trade deadline (Eugenio Suarez and Josh Naylor, most notably).

Jackson, 34, has spent the bulk of the season with the Rangers but also tossed 4 2/3 innings for the Tigers. He’s pitched to a 4.54 ERA in 39 2/3 innings overall. Once a key member of the Atlanta bullpen, Jackson was a rock in manager Brian Snitker’s 2021 bullpen as the Braves won the World Series. He tossed 63 2/3 innings with a 1.98 ERA, 26.8% strikeout rate, 11% walk rate and 31 holds. His elbow gave way the following spring, however, and Jackson missed all of 2022 following Tommy John surgery.

In three years since returning from surgery, Jackson’s results haven’t matched his pre-injury levels. He’s logged a combined 126 innings of 4.36 ERA ball. His strikeout rate is down to 23.6% in that time (and just 16.1% this year), while his walk rate climbed to nearly 12% (13.8% in 2025). Jackson’s average fastball is also down more than a mile per hour from his pre-surgery form.

Even with those red flags, he’ll get a look in the Seattle bullpen down the stretch. Jackson has plenty of experience in postseason races and high-leverage settings. That experience and his overall track record could prove beneficial for the M’s if he can get his command back on track. Jackson isn’t going to be thrust into ultra high-leverage spots anyhow, so he really only needs to function as a serviceable middle reliever.

Solano signed a one-year, $3.5MM deal over the winter. He had a dreadful start but heated up in the summer. However, Solano was signed due to his typically strong production against lefties — but struggled uncharacteristically versus southpaws (.181/.212/.245). He hit .348/.403/.478 in 77 plate appearances versus righties, but that was buoyed by a .407 BABIP he’s not likely to sustain. And, with the addition of Naylor as an everyday option at first base, the need for a short-side platoon bat at first base (who was unexpectedly struggling versus the lefties he was signed to help with) apparently ran out.

Lao, 26, made his big league debut this season but has only pitched 3 1/3 innings in the majors. He’s been tagged for three runs with a 4-to-1 K/BB ratio in that short sample. The rest of his season has been spent in Tacoma, where he’s pitched to a 3.13 ERA with a 25.9% strikeout rate and 6.7% walk rate in 69 innings of relief.

Lao, a former Dodger farmhand who signed as a minor league free agent last offseason, has averaged 93.5 mph on his four-seamer and 92.9 mph on his sinker in Triple-A. He’s also mixed in a mid-80s slider and upper-80s changeup. He has multiple minor league option years remaining and will now hit the waiver wire, where he’ll be made available to all 29 other clubs.
