Jorge Polanco won’t be back with the Seattle Mariners next season, but he left the club and its fan base heartfelt message after his signing with the New York Mets became official on Tuesday.

Morosi breaks down what could be next for Seattle Mariners’ offseason

Polanco, who signed a two-year, $40 million deal with the Mets, posted the following to his Instagram page.

#Godfirst. I cannot express with words how grateful me and my family are for the belief YOU had in me. First you traded for me and then you signed me when everyone else doubted me after surgery. YOU made me feel wanted and loved and I will be forever grateful for that. I became a better player and person because of YOU. YOU embraced my wife, kids, and me as one of your own…again, I will be forever grateful for that. YOU were an inspiration for me every night and I just wish we could have delivered you the trophy YOU deserve. I will always cherish my time with YOU…I will never forget these last two years because of YOU.

YOU= Seattle Fans, Teammates, Trainers, Coaching Staff, Front Office, and Owner.

I will always smile thinking of YOU all.

Tridents UP!

Polanco was hindered by a knee issue and had a disappointing first season with the Mariners in 2024 after he was acquired in a trade that sent four players to Minnesota. But after coming back to the M’s on a one-year deal before the start of 2025, he had a resurgent campaign that helped key the club’s run its first American League West title and AL Championship Series appearance since 2001.

After posting career worsts with a .213 average and 29.2% strikeout rate in 2024, the 32-year-old second baseman and designated hitter batted .265 with an .821 OPS, 30 doubles, 26 home runs and 78 RBIs over 138 games in 2025. His strikeout rate dropped to 15.6%, marking the largest year-to-year dip in strikeout percentage in MLB history (minimum 450 plate appearances), per MLB.com’s Mike Petriello.

Polanco was extremely clutch for the Mariners all season long. He led the league with a 1.284 OPS and 259 wRC+ in high-leverage situations, and his .438 batting average was second.

That clutch hitting showed up in the postseason as well. Polanco homered twice off two-time reigning AL Cy Young-winner Tarik Skubal during Game 2 of the AL Division Series and delivered one of the biggest hits in Mariners history with a walk-off single in the 15th inning of their series-clinching Game 5 win. He also hit the go-ahead three-run homer in Seattle’s Game 2 ALCS win.

Polanco triggered a $6 million player option for 2026 by reaching 450 plate appearances in the regular season, but he declined the option to become a free agent. He was a top offseason target for Seattle before signing with New York.
