Allan Duanne "A.J." Burnett put together a fascinating 17-season Major League Baseball career defined by blazing velocity, a devastating curveball, intense competitiveness, durability, and a unique statistical volatility. Pitching from 1999 to 2015 for the Florida Marlins, Toronto Blue Jays, New York Yankees, Pittsburgh Pirates, and Philadelphia Phillies, Burnett finished his big-league tenure with a 164-157 win-loss record, a 3.99 ERA, and 2,518 strikeouts across 2,819.1 innings.
Introduction to A.J. Burnett's Career Profile
Analyzing A.J. Burnett's MLB career statistics requires looking beyond a traditional win-loss ledger. While his 164 victories and near-even record might initially suggest a standard mid-rotation starter, Burnett was often much more dominant than his record indicated. Armed with a fastball that routinely touched the mid-to-upper 90s and a sharp, tumbling curveball, Burnett was a prototypical power pitcher who could baffle elite hitters on any given night.
At the same time, his career was marked by distinct phases. He evolved from a high-walk, high-strikeout young arm with the Florida Marlins—highlighted by a memorable no-hitter—into an integral rotation piece for a World Series champion with the New York Yankees, and finally into a resilient veteran leader who earned his lone All-Star selection in his twilight years with the Pittsburgh Pirates. Understanding his numbers requires examining his year-by-year progression, his advanced metrics, his postseason contributions, and his standing among his contemporaries.
Early Career and the Florida Marlins Era (1999–2005)
Drafted by the New York Mets in the 8th round of the 1995 MLB Draft, Burnett was traded to the Florida Marlins in 1998. He made his major league debut on August 17, 1999, at just 22 years old. During his early years in Florida, Burnett flashed immense raw talent paired with typical growing pains for a young power pitcher.
His breakout performance came on May 12, 2001, against the San Diego Padres at Qualcomm Stadium. In just his 36th career start, Burnett pitched a no-hitter, securing a 3-0 victory. However, the outing was famously unusual: Burnett walked nine batters and hit another, throwing 129 pitches while striking out seven. It remains one of the wildest no-hitters in baseball history, perfectly encapsulating his early-career battle with command.
During his time with the Marlins, Burnett underwent major arm surgery, missing significant portions of the 2003 season (including the Marlins' World Series run) due to Tommy John surgery. He returned to form by 2004 and 2005, establishing himself as a true frontline starter. In 2005, his final year in Florida, he posted a 12-12 record with a 3.44 ERA and 192 strikeouts over 209 innings, cementing his status as one of the most coveted free-agent starting pitchers on the market.
The Toronto Blue Jays Stint (2006–2008)
In December 2005, Burnett signed a lucrative five-year, $55 million contract with the Toronto Blue Jays, moving to the fierce American League East. Pitching in a hitter-friendly division against formidable lineups like the Boston Red Sox and New York Yankees presented a massive test for his power repertoire.
Despite battling various minor injuries—a recurring theme throughout his career—Burnett performed well in Toronto. In 2008, he had one of the finest seasons of his career, setting career highs in starts (33), innings pitched (221.1), and strikeouts (231), while finishing with an 18-10 record and a 4.07 ERA. His 231 strikeouts ranked second in the American League that season, trailing only teammate Roy Halladay.
Exercising an opt-out clause in his contract after the 2008 campaign, Burnett hit free agency once again, setting the stage for his high-profile move to the Bronx.
New York Yankees Years and World Series Title (2009–2011)
In February 2009, Burnett signed a five-year, $82.5 million contract with the New York Yankees. Expectations were sky-high as the Yankees sought to bolster a rotation that would lead them to a championship.
Burnett's tenure in pinstripes was characterized by extreme inconsistency. In 2009, he went 13-9 with a 4.04 ERA in the regular season, serving as a vital component of the Yankees' starting staff behind CC Sabathia. His postseason performance that October was critical: Burnett pitched effectively in the 2009 American League Championship Series and earned a crucial win in Game 2 of the World Series against the Philadelphia Phillies, helping the Yankees capture their 27th World Series title.
However, the 2010 and 2011 seasons proved deeply challenging. Burnett struggled mightily with his mechanics and confidence, posting ERAs of 5.26 and 5.15, respectively, while leading the American League in losses with 15 in 2011. Facing mounting pressure from fans and media in New York, the Yankees traded him to the Pittsburgh Pirates in February 2012.
Career Resurgence with the Pittsburgh Pirates and Philadelphia Phillies (2012–2015)
The trade to Pittsburgh revitalized Burnett's career. Freed from the intense scrutiny of the New York market, Burnett embraced a leadership role on a young, rebuilding Pirates squad and rediscovered his dominant form.
In 2012, he went 16-10 with a 3.51 ERA and 196 strikeouts, anchoring a pitching staff that changed the culture of the franchise. He followed that up with an exceptional 2013 campaign, earning his first and only career All-Star selection. That year, he posted a 10-11 record with a 3.30 ERA and 209 strikeouts in 191 innings, helping the Pirates snap their 20-year postseason drought and reach the National League Wild Card game.
After spending the 2014 season with the Philadelphia Phillies—where he logged a career-high 213.2 innings despite pitching through a sports hernia—Burnett returned to Pittsburgh for a final curtain call in 2015. In his final major league season, he was brilliant before the All-Star break, earning a spot on the NL All-Star ballot though an injury interrupted his momentum. He finished 2015 with a 9-7 record and a stellar 3.18 ERA in 164 innings, walking off the mound for the final time after starting the National League Wild Card game on October 7, 2015.

Advanced Metrics and Pitching Arsenal
Examining Burnett through the lens of advanced metrics reveals a pitcher whose talent frequently exceeded traditional ERA indicators. Throughout his career, Burnett was a premier strikeout artist. His career rate of 8.04 strikeouts per nine innings (K/9) reflects his ability to generate swinging strikes with his overpowering fastball and curveball.
However, his career was also defined by control issues. Burnett finished his career with a walk rate (BB/9) of 3.86, walking 1,211 batters total. This high walk rate contributed to elevated WHIP figures in certain seasons and forced him to navigate traffic on the basepaths frequently. Despite this, his ability to induce ground balls and escape jams kept his career homerun-to-flyball ratios manageable, especially considering he pitched in difficult ballparks and divisions for much of his career.
From a pitch-mix perspective, Burnett relied heavily on a four-seam fastball that sat at 93–95 mph and occasionally reached 97–98 mph during his prime. His primary secondary pitch was a dynamic, biting curveball that served as his primary strikeout weapon against both right-handed and left-handed hitters. Later in his career, he incorporated a sinker and a changeup more frequently to manage his pitch counts and pitch deeper into games as his raw velocity dipped slightly.
Postseason Performance and Big-Game Legacy
Burnett pitched in the postseason across multiple years with the New York Yankees and Pittsburgh Pirates. His overall playoff resume includes:
- Postseason Record: 2-3
- Postseason ERA: 4.76
- Games Started: 7
While his regular-season statistics occasionally frustrated fans due to volatility, Burnett proved his worth on the game's biggest stage in October 2009. His gritty performance in Game 2 of the 2009 World Series—where he allowed just one run over six innings against the Philadelphia Phillies—remains one of the defining pitching highlights of that championship run for New York.
