When it was announced that the Mariners would be signing Rob Refsnyder, it was made clear that he was coming to Seattle for one reason: to hit against left-handed pitching. He has a career .813 OPS against southpaws, a significant improvement over the .633 OPS he has posted against right-handed pitchers.
In 2025, the Mariners weren't bad against lefties, posting a combined .727 OPS, but his arrival signaled a different kind of roster construction, one that focused on winning on the margins. The lineup didn't have any gaping holes on paper, but small advantages over the course of a 162-game season are exactly what separate good teams from the great ones. Of course, that all sounded good on paper, but now that we're a few weeks into the season, it's clear that things aren't going as intended.
Rob Refsnyder has had little offensive impact against left-handed pitching despite it being his primary assignment
All 13 of Refsnyder's at-bats this season have come against left-handed pitching and he is currently slashing .000/.133/.000 with two walks and four strikeouts. Across such a small sample, his -57 OPS+ is almost meaningless, but it becomes more glaring when one remembers that he was brought on the team solely for this reason.
To make matters worse, it's not like he has been facing against the likes of elite lefties like Tarik Skubal, Garrett Crochet, or Cristopher Sánchez. Although he did face off against Max Fried, his struggles have come against more run-of-the-mill arms like Tyler Alexander and Reid Detmers.
In his defense, he's far from the only bat in the lineup that has gotten off to a frigid start this year. There are theories as to why a team that found itself at the top of many preseason power rankings now ranks 29th in team OPS (.607), but the main culprit is clearly a notable decrease in bat speed.
Interestingly enough, Refsnyder's bat speed this year (72.8 mph) is nearly identical to what it was last year (73.2 mph). This may seem like a good thing but it could also indicate that his issues run deeper than a simple problem with chilly weather.
It's a little early to jump to conclusions about what a player will manage to accomplish in a season after just 13 at-bats, but the Mariners' newest platoon bat hasn't given fans a lot of reasons to be hopeful. Since he'll earn just over $6 million this year and is a big-league veteran, Seattle will likely give him more of a leash, but time is running out for him to demonstrate why he was signed in the first place.
