Marlins Are Bucking MLB Trend With Unusual Pitching Approach

Tyler Phillips has been a standout in terms of his ability to excel with secondary pitches. He has thrown his splitter 373 times, accounting for 23.7% of his pitches. Opponents are batting just .133 with a .200 slugging percentage and .203 wOBA against it, while missing on 32.8% of their swings. His four-seam fastball, by comparison, has been hit at a .419 clip, albeit in a much smaller sample of 136 pitches.

The speed difference helps explain the challenge. Phillips' four-seamer averages 96.1 mph, while his splitter comes in at 87.2 mph.

Phillips isn't the only Marlins pitcher getting results with offspeed pitches. FanGraphs shows Sandy Alcantara has already thrown his changeup more than 500 times this season. That is nothing new for the 2022 NL Cy Young Award winner, who has thrown the pitch at least 700 times in three different seasons, peaking at 895 during his award-winning 2022 campaign.

Eury Pérez's changeup has held hitters to a .200 average while producing a 42.5% whiff rate, according to Statcast. He also demonstrates why the philosophy is more nuanced than simply avoiding fastballs. His four-seamer averages 98.3 mph and ranks in the 73rd percentile in fastball run value. The contrast between the two pitches allows them to play off one another. With more than eight mph separating them, hitters geared up for Pérez's upper-90s fastball risk getting out in front when the changeup arrives instead.

Fastballs remain the most common pitch in baseball. Miami is simply leveraging that reality and zigging when hitters expect pitchers to zag. Opposing teams will have opportunities to adjust as the league gets a better read on the approach, but the Marlins may also have found a strategy particularly well suited to the strengths of their staff. If so, it could become another reason to believe Miami's surprisingly competent 2026 season is more foundation than fluke.
