The Mariners announced that they have signed infielder Donovan Solano to a one-year contract. Robert Murray of FanSided reports that the ACES client will make $3.5MM this year, with $1MM in performance bonuses also available to him. Left-hander Austin Kitchen was designated for assignment to open a 40-man roster spot.
Solano, 37, has somewhat quietly been one of the better utility players in the league in recent years. Earlier in his career, he spent time with the Marlins and Yankees but didn’t hit enough at the major league level. He languished in the minors in 2017 and 2018 but got back to the big leagues in 2019 and has been hitting almost non-stop since then.
Over the past six years, Solano has played for the Giants, Reds, Twins and Padres. He got into 546 games over that stretch, stepping to the plate 1,838 times. He has managed to produce a batting line of .294/.353/.413 in that time, which translates to a wRC+ of 112, indicating he’s been 12% above league average overall.
For those years, he has a combined .360 batting average on balls in play. That would normally be a concern, since the league average is usually below .300, but he’s been maintaining high BABIPs for several years now. Of the six most recent seasons, his BABIP bottomed out at .321 in 2021. He was at .346 or higher in the other five seasons. That suggests the numbers are more a reflection of his swing than mere luck.
Solano won’t provide huge power, with last year’s eight home runs actually marking a career high. His walk rates aren’t especially strong either. However, his style of offense could be a good fit for Seattle, as that club has been wary of its strikeout problems for a while now.
Going back to the 2023 club, guys like Mike Ford, Jarred Kelenic, Teoscar Hernández, Eugenio Suárez and Tom Murphy were not brought back after posting strikeout rates north of 27%. But Seattle didn’t find the improvements it was looking for in that category last year, with guys like Luis Urías, Mitch Garver, Mitch Haniger, Jorge Polanco and Randy Arozarena striking out more than 28% of the time after being brought aboard. Solano has a career strikeout rate of 18.9% and has never had that number finish higher than 22.2% in any individual season.
The Mariners have clearly been looking for infield help this winter. Justin Turner hit free agency. Josh Rojas was non-tendered. The M’s turned down a club option on Polanco. That left them with J.P. Crawford at shortstop and question marks elsewhere.
Solano has played all four infield spots in his career but hasn’t played shortstop since 2021. He has more experience at second base than anywhere else but has spent more time at the corners in recent years.
That flexibility gives the Mariners some options in terms of how Solano is deployed. Reporting this winter has suggested the club may feel it has enough in-house options to cover second base, with Dylan Moore and Ryan Bliss potentially covering there until prospect Cole Young seizes the job. Luke Raley is an option to be the strong side of a platoon at first, since he’s a lefty swinger with notable splits. Guys like Austin Shenton, Tyler Locklear, Samad Taylor and Leo Rivas are also capable of playing various infield positions and on the 40-man roster.
The M’s are likely not done adding to that group, so Solano’s role could well be determined by what other moves are forthcoming. He could take some playing time at second or third, while his right-handed bat could also allow him to shield Raley from lefties at first base. Solano has fairly neutral platoon splits for his entire career, with a 101 wRC+ against lefties and 98 wRC+ otherwise. However, he’s been a bit more extreme in his recent resurgence. Over the past six years, he has slashed .310/.361/.444 against lefties for a 122 wRC+, compared to a .285/.349/.395 line and 107 wRC+ against righties.
It has been reported this offseason that the M’s were working with about $15-16MM of payroll space. Solano will use up a small portion of that while strengthening the infield group. That still leaves with them with some powder dry for another infield addition. It was previously reported that they were interested in bringing back Turner, though it’s possible the Solano signing makes that harder to put together.
It’s also possible that the M’s make a bold move to totally remake the picture, as there have been rumors they could trade Luis Castillo as a means of freeing up some spending capacity. Whether they go that route or simply find another modest infield addition remains to be seen. Pitchers and catchers will be reporting to spring training in about a month.
Kitchen, 28 next month, has limited big league experience. A prospect in the Rockies’ system, he was selected to the big league roster in June but was designated for assignment the next day without getting into a game. He went to the Marlins via waivers and made four appearances for that club, allowing 11 earned runs in seven innings. A second DFA in September put him back on waivers, which led the Mariners to put in a claim.
Though Kitchen has an ugly 14.14 earned run average, it’s a tiny sample of major league work. His minor league track record has generally been solid, with the lefty keeping the ball on the ground. In 2024, pitching for three organizations, he logged 52 1/3 innings in the minors. In that time, he had a 3.78 ERA, 15.1% strikeout rate, 6.8% walk rate and 55.1% ground ball rate.
The M’s will now have a week to figure out what’s next for Kitchen, whether that’s a trade or another trip to the waiver wire. The waiver process takes 48 hours, so any trades would have to come together in the next five days. Kitchen still has a couple of option years and minimal service time, so a club willing to give him a roster spot could keep him as cheap depth for the foreseeable future.
