The knuckleball is one of baseball’s most enigmatic pitches, a floating, dancing oddity that confounds batters and catchers alike. Throughout the history of America’s pastime, a select few pitchers have mastered this difficult art, using it to achieve remarkable success and longevity. Here’s a look at the ten best knuckleball pitchers of all time:

1. Phil Niekro (1964-87): Known affectionately as “Knucksie,” Niekro is the undisputed king of the knuckleball. A Hall of Famer, he pitched for an astounding 24 seasons, amassing 318 wins (16th all-time) and 3,342 strikeouts (11th all-time) with a stellar 3.35 ERA. Niekro’s mastery of the knuckleball allowed him to pitch effectively well into his 40s.
2. Hoyt Wilhelm (1952-72): Another Hall of Fame inductee, Wilhelm’s career is a testament to the knuckleball’s ability to extend a pitcher’s career. He pitched until he was nearly 50, becoming the first player to appear in 1,000 games and reach 200 career saves. Wilhelm finished with 143 wins, 228 saves, and an impressive 2.52 ERA.
3. Tim Wakefield (1992-2011): The face of the knuckleball in recent memory, Wakefield spent most of his 19-year career with the Boston Red Sox. He racked up 200 wins and 2,156 strikeouts, earning an All-Star nod at 42 and winning two World Series rings. Wakefield’s success helped keep the knuckleball relevant in the modern era.
4. Charlie Hough (1970-94): Hough’s 25-year career is a marvel of consistency and durability. He won 216 games with a 3.75 ERA and 2,362 strikeouts, throwing an impressive 107 complete games. Hough’s All-Star appearance for Texas in 1986 showcased the knuckleball’s continued effectiveness in the 1980s.
5. R.A. Dickey (2001-17): Dickey’s career is a testament to perseverance and the transformative power of the knuckleball. After struggling as a conventional pitcher, he reinvented himself with the knuckler, culminating in a Cy Young Award-winning season in 2012 – the only knuckleballer to achieve this honor.
6. Wilbur Wood: The sole left-handed knuckleballer on this list, Wood’s career was marked by an impressive streak of consecutive 20-win seasons and All-Star appearances. His unique combination of handedness and pitch selection made him a formidable opponent on the mound.
7. Dutch Leonard: A pioneer of knuckleball success, Leonard demonstrated remarkable control and longevity with the pitch. His ability to remain effective well into his 40s set a precedent for future knuckleballers.
8. Joe Niekro: Following in the footsteps of his more famous brother Phil, Joe used the knuckleball as a complementary pitch to great effect. He found particular success with Atlanta and Houston, carving out his own niche in knuckleball history.
9. Tom Candiotti: Known for his consistency and endurance, Candiotti was a reliable knuckleball specialist throughout his career. His standout 1991 season highlighted the pitch’s potential for dominance when mastered.
10. Bob Purkey: Purkey’s career exemplifies the knuckleball’s ability to revitalize a pitcher’s fortunes. After a modest start with the Pirates, he found success with the Reds, eventually earning induction into their Hall of Fame.

These ten pitchers stand out not just for their mastery of the knuckleball, but for the way they used this unconventional pitch to achieve greatness. Their careers demonstrate the unique advantages of the knuckleball: the ability to pitch effectively at advanced ages, to reinvent oneself mid-career, and to confound batters with a pitch that seems to defy the laws of physics. As baseball continues to evolve, the legacy of these knuckleball masters serves as a reminder of the sport’s capacity for wonder and unpredictability.
