Mariners Gold Glover has completely flatlined as a useful player in 2025

Seattle Mariners fans seem to have a love-hate relationship with Dylan Moore. The utility man has been with the M's since Opening Day of 2019, making him the longest tenured player on the roster. Known for his streaky bursts of offense, Gold Glove-caliber defense at multiple positions and speed on the basepaths, Moore has managed to stick with the M's for seven years.

Despite that, he has never proved himself as an everyday player. And as a bench piece on an expiring contract, his time in Seattle could be limited.

Dylan Moore has been testing the Mariners' commitment to him

Moore started the season on a ridiculous hot stretch. He had a .903 OPS in the month of April, belting six home runs and swiping five bags. Since then, he has gone completely cold.

In fact, since April 19th, Moore sports an OPS of .594. He finished May at .682, but in June has been almost completely useless. So far, nearly two-thirds of the way into the month, Moore is slashing .050/.136/.050, good for a .186 OPS. He just recorded his first hit of the month on Wednesday afternoon against the Boston Red Sox. It was his first base-knock since May 27th.

The underlying numbers do not do Moore any favors. According to Statcast, he is in the first percentile in strikeout percentage in 2025. He is striking out at a higher rate than nearly everyone else in baseball at 32.7 percent of the time he steps up to the plate. He's in the 11th percentile in whiff rate (31.5 percent).

What's interesting is that Moore's chase rate and walk rates look fine. He is walking at a slightly above average clip of 8.5 percent, and his chase rate is in the 60th percentile.

Which means the problem is not swing decisions. The problem lies within the swing. One metric that is particularly revealing is Moore's squared-up rate. The infielder is squaring up the baseball just 17.8 percent of the time, which falls into the first percentile. Other metrics that are down include Moore's hard-hit rate of 35.1 percent, which ranks in the 20th percentile, and his average exit velocity of 85.6 miles per hour, in the fourth percentile.

Simply put, Moore is not holding his own at the plate. He is striking out far too often, not squaring up the ball and not hitting the ball hard enough.

His defense has also taken a turn for the worse. Just last year, Moore won a Gold Glove, but this year he has looked slower than usual in the field. Statcast agrees, giving him a career worst -3 Fielding Run Value, in the 19th percentile. His range and arm strength both rank in the tenth percentile.

Even his baserunning, usually a strong suit, has taken a hit. He has a Baserunning Run Value of 0, making him a league-average baserunner.

If Moore is not able to field, run or hit at the levels he used to, how much longer will the utility man remain on the team? He is signed through the end of the year and will then become a free agent. It feels more and more like Moore's time in Seattle might be nearing an end if he can not make himself a more valuable ballplayer soon.
