Fantasy Baseball: Five Pitchers Primed for Breakout in 2026

In this fantasy baseball preview, veteran scribe Tristan H. Cockcroft urges managers to take it slow early in the 2026 season. He suggests using advanced metrics to spot breakout arms before the crowd does.

The piece mixes some healthy skepticism about small samples with data-driven tips for evaluating starters who haven’t racked up many innings yet.

Patience pays off: reading early-season numbers

Cockcroft says don’t get carried away by a single outing. Tiny samples can still tip you off to real breakout candidates, but it’s easy to get fooled.

He points out that while not every hot start means much, advanced metrics can help you tell the difference between a mirage and a pitcher with real upside. For lightly used arms, you want to watch swing-and-miss rates, velocity jumps, and new pitches in their repertoire.

Those are the things that hint at meaningful fantasy value in 2026, even if the box score isn’t flashy yet.

How to apply advanced metrics when size matters

If you’re managing a roster, keep an eye on swinging-strike rate and whiff rate—not just the box score. A pitcher who’s added a sharper cutter, a new breaking ball, or a few ticks of velocity might be worth a speculative add, even if he’s only thrown a handful of innings.

Cockcroft points out that lightly used starters can turn into fantasy gold once the metrics start to back up the hype.

Rising candidates to watch: young talents and seasoned performers with upside

There are a handful of arms who could swing fantasy leagues this year, whether it’s with a breakout or just a step forward. From Yankees prospects to Dodgers’ surprises and some intriguing international names, there’s a common thread: improved repertoires and better whiff rates might unlock big value in 2026.

• Schlittler — The Yankees prospect made noise with a 25-point MLB debut, showing a fastball up near 98 mph and a nasty cutter to lefties. He’s only got 17 MLB starts, but if things break right, he could flirt with a top-10 fantasy ceiling this season.
• Shohei Ohtani — After the WBC, he looked set as a full-time starter for the Dodgers. He logged 61 and 86 pitches in spring, then tossed six shutout innings in his opener. If he keeps building up innings, we might even see a 1,000-point fantasy season—which sounds wild, but who’s betting against him?
• Imanaga — His debut wasn’t perfect, but he tweaked the sweeper, splitter, and added a little fastball velocity. That led to a strong spring: a 20.1% swinging-strike rate and a 39.5% whiff rate in his first outing. There’s a real chance he gets back to or even tops his 2024 form.
• Connor Burns — He put “piggyback” concerns to rest with five innings of one-hit ball and seven punchouts. His whiff rates are elite, and with a 98+ mph fastball and a slider that misses bats, he’s a high-upside play—just be aware the innings could be capped.
• Paul Skenes — Opening Day didn’t go well, but Cockcroft says don’t panic. The pitch metrics looked the same, and factors like defense or sample size can really skew early results.
• Michael Leiter — He’s added a cutter to his arsenal, which already includes a 97+ fastball and a killer changeup. That’s translated into more strikeouts. After a strong finish to 2025, he’s got a legit shot at ending up as a top-25 starter.

Target now, if available: seize the upside before prices rise

Cockcroft says it’s smart to hang onto pitchers you already have. But if you spot one of these arms on the wire, don’t wait—grab them before everyone else catches on.

Early numbers are hinting at a few under-the-radar pitchers. These guys have sharpened their repertoires and seem to be missing more bats, which could mean real fantasy value in 2026.
