Some pitches are simply unfair. The curveball, when thrown right, can drop jaws, buckle knees, and freeze even the most disciplined hitters. Over the decades, a few arms have made the curveball into a work of art, using it to dominate lineups and carve their names into baseball history.
Here are 10 of the most devastating curveballs ever thrown, pitches that made the best hitters in the world look absolutely silly.
10. Sandy Koufax – The Blueprint of Breaking Balls
Koufax’s curve wasn’t fair. Described as “falling off a table,” it helped him throw four no-hitters and dominate in October. He made Hall of Famers look helpless, and changed the way pitchers approached the game.
9. Bert Blyleven – Curveball Hall of Famer
Blyleven’s curve was so good, it’s arguably the main reason he made the Hall. It had deep, vicious break that hitters couldn’t predict or time. Over 3,700 strikeouts later, it still holds up as one of the greatest.
8. Clayton Kershaw – The Signature Snap
Kershaw’s curve is pure magic. With a sharp, downward bite, it’s been fooling hitters for over a decade. It’s the pitch that’s defined his Hall of Fame career, and it’s still working in 2025.
7. Dwight Gooden – Teenage Terror
At just 19, Doc Gooden was unhittable. His curveball, nicknamed “Lord Charles” was devastating. Paired with a high-90s fastball, his breaking ball helped him strike out 276 in his rookie year.
6. Nolan Ryan – Power + Break = Nightmare
While known for his fastball, Nolan Ryan’s curveball was a monster in its own right. Hitters sat dead red, and then got served a heavy, looping hook that made them look foolish.
5. Dennis Martinez – El Presidente’s Disappearing Act
Martinez made a perfect game look routine with his deadly off-speed stuff. His curve was sharp, quick, and completely unhittable when it was on, leaving batters confused and off-balance.
4. Mike Mussina – The Professor’s Precision
“Moose” didn’t overpower hitters, he outthought them. His curve was a chess move, darting in at the knees when batters expected heat. It was especially deadly in two-strike counts.
3. Barry Zito – The Big-Break Beauty
Zito’s curve wasn’t just effective, it was mesmerizing. With absurd arc and late drop, it was nearly impossible to square up. It helped Zito win a Cy Young Award and earn over $100 million in his career.
2. Adam Wainwright – The “Uncle Charlie” That Ends Careers
Wainwright’s curveball is one of the most iconic pitches in postseason history. Just ask Carlos Beltrán, who froze up on one in Game 7 of the 2006 NLCS. Waino’s 12-6 breaker defined an era of Cardinals pitching.
1. Camilo Pascual – The Original Curveball Artist
Before modern MLB mechanics and analytics, Camilo Pascual wowed with a curve that dropped off the table. Ted Williams once called it the best he ever saw, high praise from arguably the best hitter ever.
These legendary MLB hurlers turned a simple breaking ball into baseball sorcery. From Koufax to Kershaw, their curveballs weren’t just effective, they were defining. When thrown right, a curveball doesn’t just beat hitters. It embarrasses them.
