Top Young Phillies Pitchers Under 25
The Phillies’ future on the mound is brighter than it’s been in years — and much of that promise comes from pitchers under 25. Right now, the best Phillies pitchers under 25 aren’t just names on a prospect list; they’re turning heads in spring training, dominating Double-A hitters, and earning late-inning roles before their 26th birthday. This isn’t about hypothetical upside — it’s about performance, polish, and presence. We’re spotlighting the young arms who’ve earned the label: the best Phillies pitchers under 25.
Ranger Suárez: The Quiet Anchor (Age 24)
Ranger Suárez doesn’t flash triple-digit heat or headline top-100 lists — but he wins. At 24, he’s already logged over 300 MLB innings with a career 3.71 ERA, and his 2023 season (3.45 ERA, 1.18 WHIP across 151 IP) proved he’s more than a lefty specialist. What makes Suárez one of the best Phillies pitchers under 25 is his command, sequencing, and poise — especially against right-handed lineups. He throws five pitches with conviction, mixes speeds like a veteran, and rarely wastes a pitch. His age puts him squarely in this group — and his consistency makes him the steady heartbeat of Philly’s young rotation core.
Andrew Painter: The Ace-in-Waiting (Age 21)
When Andrew Painter was drafted 13th overall in 2021, scouts saw a rare blend: mid-90s sinker, wipeout slider, and a changeup that already looks MLB-ready. Injuries slowed his ascent, but his 2024 spring performance — 11 Ks in 9.1 innings, zero walks — reminded everyone why he’s still considered the franchise’s top pitching prospect. At 21, Painter’s stuff grades out as elite, and his delivery has smoothed out dramatically since his rehab last year. He’s not just one of the best Phillies pitchers under 25 — he’s arguably the most electric arm in the entire system. Expect his debut before midseason, and expect impact.
Mauricio Llovera: The Late Bloomer With Late Life (Age 24)
Mauricio Llovera didn’t crack the Phillies’ radar until he was 22 — signed as an international free agent out of Venezuela with little fanfare. Fast forward two years: he’s posted sub-2.00 ERAs in both High-A and Double-A, mixing a low-90s cutter, sharp curve, and deceptive changeup. At 24, Llovera’s control has sharpened, his stamina has grown (he threw 112 innings last year), and his composure in high-leverage spots stands out. He’s not a name you’ll see in every national top-100 list — but within the organization, coaches call him ‘the quiet weapon.’ He fits perfectly among the best Phillies pitchers under 25 because he’s delivering now, not just projecting later.
Noah Skirrow & Other Names to Watch
Noah Skirrow (23) made a strong impression in 2023 at Reading — posting a 2.87 ERA with 10.4 K/9 and holding lefties to a .192 average. His fastball sits 93–95 mph, and his slider has evolved into a true swing-and-miss pitch. He’s not quite ready for the big leagues, but he’s knocking. Then there’s Jhailyn Ortiz (22), a converted infielder turned hard-throwing reliever whose 98 mph heater and fearless approach have scouts buzzing. And don’t sleep on Tyler Durna (24), who quietly posted the lowest walk rate in the Eastern League last season. These aren’t just depth pieces — they’re part of what makes the pool of best Phillies pitchers under 25 deeper and more dynamic than in recent memory.
