Despite some glaring needs for offense, the Mariners only ended up tinkering a bit with their lineup after a pretty quiet offseason.

Notable Losses

After a few months of scouring the free agent and trade markets for a replacement for second baseman Jorge Polanco, the Mariners ended up signing….third baseman Jorge Polanco, brought back on a one-year deal worth $7.75MM in guaranteed money, and with a vesting option that could guarantee Polanco at least $6MM in 2026.  Polanco has played the vast majority of his nine MLB seasons as a middle infielder, but he does have 24 games of experience as a third baseman, with 15 of those games coming as recently as the 2023 season when he was still a member of the Twins.

Polanco’s defensive metrics as a second baseman were mostly subpar, and his lack of a strong throwing arm raises questions about how well he’ll translate to the hot corner.  However, the bigger issue might be whether or not Polanco can rebound from a rough year at the plate.  The infielder hit only .213/.296/.355 over 469 plate appearances with Seattle in 2024, while also missing a month due to a hamstring strain, and undergoing surgery in October to correct a lingering left knee problem.

SEATTLE – The wait has been long, but it’s nearing its end for Seattle Mariners minor league outfielder Jonny Farmelo.

Farmelo is one top prospects in the M’s organization, but his first pro season came to an abrupt end last June when he suffered a torn ACL in his right knee catching a fly ball in center field for the Single-A Modesto Nuts.

M’s reassign top prospect amid several roster moves

At the time, the 2023 first-round pick was enjoying a strong first couple of months as a 19 year old in the California League. In 46 games, he slashed .264/.398/.421 with 10 doubles, three triples, four home runs and 18 stolen bases.

While the injury derailed what was a promising debut season as a pro, Farmelo has focused on the positives that have come with his rehab process.

“I’ve grown a lot as a person and as a player as well,” he said Sunday during the Mariners’ opening week warm-up event at T-Mobile Park. “And I believe that even though I missed a lot of time, that I could come out of this injury better and it could be a good thing for my career. So I’m excited.”

As for the status of his knee?

“The knee is doing great,” Farmelo said. “We’re almost nine months post-op. I’m moving around, I’m swinging, I’m throwing, I’m doing a lot of everything.”

Farmelo still hasn’t reached the point of playing games, which made gearing up for the season in Arizona this spring bittersweet. He said expects to make his return to the minors in “a few months.”

“It’s not too bad when you’re there kind of alone in Arizona. When everyone comes and they’re playing and you’re not doing anything, that’s when it gets hard,” Farmelo said. “So that was tough, but I’m trying to focus on the good, and there’s been a lot of it.”

One of the good things is that Farmelo’s injury hasn’t seemed to have too much impact on his prospect status. He’s still the sixth-ranked prospect in the M’s farm system and No. 92 in all of baseball, per MLB Pipeline. However, the speedy left-handed hitter isn’t all that interested in those sort of accolades.

“I could care less about what my prospect ranking is, to be honest with you,” Farmelo said. “I’m just trying to play and compete and get to the big leagues. It’s definitely cool to see, but I don’t want to pay too much attention to it.”

There is one thing Farmelo is putting a lot of attention on, though.

“I think the biggest focus (this season) is to just stay on the field and, most importantly, just do everything I can to stay on the field – because some things happen like the knee injury that you can’t really control,” Farmelo said. “So just trying to stay on the field and get at-bats. I’m not really putting too much expectations on this year. I just want to play.”

A week where young player after young player was whittled from the Seattle Mariners’ camp roster as they work their way towards identifying the final 26 for opening day ended with the release of one of its most veteran players – Mitch Haniger.

Insider: How Seattle Mariners stack up in wide-open AL West

The Mariners announced the release of Haniger before their penultimate spring training game Sunday morning.

“Mitch has been a significant part of Mariners history and will be missed,” Mariners president of baseball operations Jerry Dipoto said in a press release. “The day he arrived for his first spring training back in 2017, he established himself as one of the most focused, prepared, and hardest working players I’ve ever been around. We all appreciate the many ways he’s made us all better, on the field and off.”

Originally acquired from the Diamondbacks along with Jean Segura and Zac Curtis in a November 2016 trade, it was the then-lesser-known Haniger that would leave the biggest mark on the Mariners. Among his accomplishments with the team, Haniger leaves as the record holder for walk-off hits with eight, each a memorable moment for the team and fans alike.

“Putting on a Mariners uniform and playing at T-Mobile Park is something I’ll cherish forever,” Haniger said. “To our fans, my teammates, and everyone a part of this organization, thank you for embracing my family and me. We have so many great memories to look back on.”

When Jerry Dipoto embarked on the “step back” plan following the 2018 season, Haniger was one of the few players not dealt away. The intent was to keep the player teammates called “our champion,” as the example for the young players they anticipated coming up.

While he has had many memorable moments and set career highs in home runs (39), RBI (100) and runs scored (110) with the team, injuries have also been a part of his story. His latest, shoulder discomfort, has kept him from games since March 8. With the roster crunch it was hard to see how playing time would be found for the 34 year old, and the move was made with the club to pay the remaining $15.5 million remaining on the final year of his contract.

Thank you for everything you’ve done for our organization, fans and the community, Mitch.

Wishing you nothing but the best in the next chapter of your journey. pic.twitter.com/225rlO3M5Q
