What the Strider Comparisons for Fuentes Get Right — and What They Miss

Seventeen strikeouts in nine innings, zero hits allowed, one baserunner — a hit-by-pitch that Didier Fuentes immediately erased by retiring the next twenty-six batters he faced. Those are spring training numbers, which means they come with the usual disclaimers. But the reason everyone is talking about the twenty-year-old Colombian right-hander this week has less to do with the stat line itself and more to do with whose stat line it reminds them of.

The Spencer Strider comparison has become the default frame for understanding Fuentes. Manager Walt Weiss endorsed it himself: "There's some parallels there. For sure. The way that Strider broke in." MLB.com ran a feature on it. Battery Power mapped the pitch arsenals side by side and found them "nearly identical." The comparison is everywhere, and it isn't wrong. It's just incomplete.

Start with what it gets right, because there's real substance here. Both pitchers are built on the same two-pitch foundation: a power fastball in the upper nineties and a hard slider that generates swings and misses at elite rates. Fuentes is sitting 97.2 mph on the fastball this spring, touching 99. Strider, in his 2022 rookie year, lived in that same velocity band, routinely reaching 97-99 before the internal brace procedure slowed him down. Fuentes's slider — now averaging 87 mph with a 50% whiff rate in spring — has undergone a dramatic transformation from the low-80s sweeper he threw in the minors, and it's become the kind of pitch that, paired with that fastball, makes hitters look structurally overmatched.

The developmental path rhymes, too. Strider started in the bullpen in 2021 and early 2022 before transitioning to the rotation on May 30. Fuentes is making the Opening Day roster as a long reliever before heading to Triple-A Gwinnett to stretch out as a starter. Both had limited minor league seasoning — Strider made only twenty-two minor league appearances before his call-up; Fuentes was pitching Double-A at nineteen. The Braves are running the same playbook. That part of the comparison is structural, not hype.

Now here's where it gets complicated.

Strider was twenty-three when he arrived in 2022, a Clemson product with a college degree and three additional years of physical maturity that most people gloss over when they line up the two names. Three years at that age is enormous — it's the difference between a body that's finished developing and one that's still figuring out what it is. Fuentes turned twenty last June. He signed for $75,000 as a sixteen-year-old out of Tolu, Colombia. The raw ability is obvious. The finished product is not.

The numbers at each level tell a story about that gap. Fuentes posted a 32.1% strikeout rate at Low-A in 2024, where he was the best arm in the Braves' system over seventy-five innings with a 2.74 ERA and 1.02 WHIP. That rate dipped to roughly 30% at High-A, then to approximately 25% at Double-A — the level where hitters start sitting on fastball-slider patterns and punishing the ones that don't have a third option. His four MLB starts last year were honest about where he stood: 13.85 ERA, twelve strikeouts but six walks in thirteen innings. Strider never had an equivalent failure. He struck out 202 batters in 131.2 innings as a rookie — the fastest pitcher in major league history to reach 200 strikeouts — and he did it while posting a 2.67 ERA. The trajectory was immediate. Fuentes's is not.

Then there's the question that Battery Power posed directly: where's Didier Fuentes's curveball?

Strider had a changeup as his third pitch in 2022, and later developed a curveball that gave him the arsenal depth to survive a lineup for the third time through the order. Fuentes has a splitter that he mixes in occasionally, but his curveball — which exists, and which looks promising in minor league footage — is, as one evaluator put it, "probably left in Gwinnett for now." The distinction matters more than any velocity reading. A two-pitch arm, no matter how electric, has a ceiling that looks like the back end of a bullpen, not the front of a rotation. Whether Fuentes can develop that third pitch will determine whether the Strider comparison ages as prophecy or as the kind of flattering spring training narrative that baseball produces every March and forgets by June.

I wrote earlier this week that the Braves go exactly as far as Strider's arm takes them in 2026. That remains true. But if Strider's spring velocity — now back in the 97-99 range, nearly two ticks ahead of his 2025 marks — holds through April and his slider whiff rate stays above 40%, then the Fuentes comparison shifts from present tense to aspirational future. Fuentes isn't Strider yet. He might never be. What he is, at twenty years old with a fastball that touches 99 and a slider that's moved five miles per hour harder in a single offseason, is a reason to pay attention.

Baseball has a long memory. The franchise that developed Maddux, Glavine, and Smoltz into a rotation that defined an era knows what pitching development looks like — and knows it doesn't happen in nine spring innings. It happens over seasons, over mechanical adjustments, over the slow accumulation of a third pitch and a fourth pitch and the command to use them when the count isn't in your favor. The comparison to Strider is where Fuentes's story starts. It isn't where it ends.
