Mariners designate Kolten Wong for assignment, Red Sox interested

The Mariners have designated second baseman Kolten Wong for assignment, per MassLive’s Chris Cotillo. Wong’s stay in DFA limbo could be a short one, as the Red Sox have interest in a trade for the veteran infielder.

Wong, 32, came over to Seattle in the swap that sent Jesse Winker and Abraham Toro to Milwuakee this past offseason. The Mariners acquired him hoping he could solidify second base for them, but things didn’t go according to plan as Wong posted by far the worst season of his career in 2023. 

In 216 trips to the plate this season, Wong has batted a brutal .165/.241/.227 that checks in 64% worse than league average by measure of wRC+. That unplayable offense has been paired with below average defense at the keystone, combining to create a package worth -1.0 fWAR in 67 games with Seattle this season.

Prior to this disastrous season in Seattle, Wong had spent the past nine season as a quality, major league regular at second base. After being drafted 22nd overall by the Cardinals in the 2011 draft, Wong made his MLB debut in a 32-game stint with St. Louis during the 2013 season. 

He became a fixture at second base in 2014 and would remain there for seven seasons, slashing .263/.336/.389 (98 wRC+) over that time while winning the NL Gold Glove at second base in both 2019 and 2020.

Following the 2020 campaign, Wong tested free agency for the first time in his career and landed with the Brewers on a two-year deal. His defense took a step back during his time in Milwaukee, as he rated as roughly average in 2021 and landed in just the third percentile among qualified fielders by measure of Outs Above Average last year. 

That slip in terms of defensive value was made up for by improved performance at the plate, as Wong slashed .262/.337/.439 with a wRC+ of 113 in 989 plate appearances during his two seasons with Milwaukee.

While Wong has struggled badly in Seattle, that extensive track record as an above-average regular has evidently caught the attention of the Red Sox, who have struggled to get production out of their middle infield with shortstop Trevor Story having missed the entire season to this point. 

They’ve relied on a variety of options up the middle this season, including Enrique Hernandez, Yu Chang, Christian Arroyo, Pablo Reyes and Enmanuel Valdez. 

As for the Mariners, Dylan Moore, Jose Caballero, and the newly-acquired Josh Rojas are among the club’s options at the keystone going forward.
