Roger Clemens. “The Rocket.” The nickname alone tells you almost everything you need to know. Over 24 major league seasons, Clemens won 354 games, struck out 4,672 batters, captured a record seven Cy Young Awards, won an American League MVP Award, claimed two pitching Triple Crowns, and led his league in ERA six different times.
As of 2026, he ranks third all-time in career strikeouts, ninth in wins, and among the greatest pitchers the game has ever seen by virtually every meaningful measure. Few
pitchers in baseball history can match the combination of longevity, dominance, and hardware Clemens accumulated. Even fewer have remained as polarizing.
William Roger Clemens
Born: August 4, 1962 (Dayton, OH)
Yankees Tenure: 1999-2003, 2007
Before he became “The Rocket,” Clemens was simply a kid from Dayton, Ohio. While he was still in high school, his family moved to Texas, the state he would then forever call home. Clemens excelled in baseball, football, and basketball at Spring Woods High School before attending JUCO power San Jacinto College. He eventually transferred to the University of Texas, where he cemented himself as one of the nation’s top collegiate pitchers.
Clemens capped off his collegiate career in storybook fashion in 1983. In his final game, he threw a complete game to lead the Longhorns to the College World Series championship. Just days earlier, the Boston Red Sox had selected him with the 19th overall pick in the MLB Draft.
The Red Sox wasted little time bringing Clemens to the majors, and he debuted in 1984. Over the next 13 seasons, he became the face of Boston’s staff and one of the most feared arms in baseball. His legendary 1986 season remains one of the greatest ever by a starting pitcher, as he captured the American League MVP Award, the Cy Young Award, and All-Star Game MVP honors.
During his time in Boston, Clemens won three Cy Young Awards, earned five All-Star selections, led the American League in ERA four times, and topped the league in both wins and strikeouts three times (fanning a record 20 in a game twice). He established himself as a Red Sox legend and one of the players Yankees fans loved to hate. Truly you can almost guess a Yankees fans age based on their immediate reaction to hearing Clemens name.
After the 1996 season, Boston let Clemens walk, a decision that immediately came back to haunt the franchise. Clemens signed a then-record three-year contract with the Toronto Blue Jays and somehow reached an even higher level of production. In both 1997 and 1998, he captured the pitching Triple Crown by leading the American League in wins, ERA, and strikeouts. He won the Cy Young Award in both seasons, made the All-Star team each year, and erased any doubt that he remained the most dominant pitcher in the sport.
Following the 1998 season, Clemens was traded for the first time in his career, landing with the defending World Series champion Yankees. On February 18, 1999, Brian Cashman sent fan favorite David Wells to Toronto in exchange for the game’s biggest pitching prize. The move still provokes an uneasy feeling among some fans today.
Clemens immediately raised expectations for an already dominant club. His first regular season in New York had its bumps, but when October arrived, so did The Rocket. In Game 4 of the 1999 World Series, Clemens threw 7.2 brilliant innings against the Braves to finish off the sweep and finally earn the first World Series championship of career.
The 2000 season only added to his legend, and it wasn’t the cause of the 15-K, one-hit shutout he spun in Seattle in the playoffs. During a regular-season game in July, Clemens struck Mike Piazza in the helmet with a fastball, forcing the Mets star to miss the All-Star Game. The incident set the stage for one of the most memorable moments in Subway Series history. Then in Game 2 of the World Series in a fateful Subway Series matchup against those same Mets, Piazza shattered his bat on an inside pitch. As the barrel spun toward the mound, Clemens picked it up and fired it down the first-base line as Piazza sprinted out of the batter’s box, creating one of the most replayed moments in Yankees history. (Lost in all of it was that Clemens also threw eight shutout innings to help the Yanks get a 2-0 lead.)
If 2000 cemented Clemens as a Yankees legend, 2001 may have been his finest regular season in pinstripes. Clemens became the first pitcher in major league history to begin a season 20-1, ultimately finishing 20-3 with a 3.51 ERA while capturing his sixth career Cy Young Award. This season still stands as one of the best individual performances by any Yankees pitcher in terms of wins and losses (even if other metrics favored new teammate Mike Mussina for the Cy that year).
Then in 2001, following the attacks of September 11th, Clemens helped carry the Yankees back to the World Series. In Game 7 against the Diamondbacks, he battled Curt Schilling pitch for pitch, striking out 10 over 6.1 outstanding innings before leaving with the game tied at 1-1 and the Yanks soon to seize the lead on an Alfonso Soraino homer off Schilling. Arizona would ultimately rally against no less than Mariano Rivera, denying Clemens what would have been another championship and one of the best sport stories of all-time.
After a somewhat injury-limited 2002 campaign, Clemens reached two of baseball’s most sacred milestones in 2003. On a Friday night at the original Yankee Stadium, he struck out Edgar Renteria for career strikeout No. 4,000 before securing his 300th career victory later that evening. Fittingly for a pitcher who always seemed to want to be on baseball’s biggest stages and be the headliner, Clemens became the first pitcher in MLB history to reach both milestones in the same game.
Throughout 2003, Clemens said that he would retire at season’s end, and after receiving an ovation in Miami while leaving the mound during the World Series upset loss to the Marlins, the game bid him adieu. It didn’t take. Friend and teammate Andy Pettitte had signed with the Astros in free agency when the Yankees oddly didn’t pursue him with much vigor, and after thinking about it, Clemens decided to make a comeback close to home.
Clemens returned to Houston following the season and immediately added another chapter to his remarkable career. I am not joking when I say I think Lebron took a page out of Clemens book when it came to trying to make his career a storyline fit for a movie.
At age 42, he became the oldest pitcher ever to win a Cy Young Award after posting an 18-4 record with a 2.98 ERA in 2004. The following season, he led all of baseball with a microscopic 1.87 ERA while helping guide the Astros to the first World Series appearance in franchise history, though a hamstring injury in Game 1 paced a White Sox sweep.
Three years after leaving New York, Clemens authored one final memorable Bronx moment. During the seventh-inning stretch of a May 6, 2007, game against Seattle, the stadium video board suddenly came to life as Clemens appeared from George Steinbrenner’s suite and simply told the crowd, “Thank you… I’m back.” A moment I remember being way, way too excited about in hindsight.
His second Yankees stint lasted 17 starts and far less of a fun ride than the first—he was 45 when he threw his final pitch and it showed, leaving with an injury in the 2007 playoffs—but it brought his New York totals to 83 victories, 1,014 strikeouts, six postseason appearances, two World Series championships, one Cy Young Award, and one of the most memorable runs any Yankees pitcher has ever enjoyed.
No discussion of Clemens’ career is complete without acknowledging the cloud that followed him towards the end of his career and after retirement. Allegations of performance-enhancing drug use and the Mitchell Report (not to mention other, worse off-field questions) overshadowed his final years in baseball and have kept him outside the Hall of Fame despite his technical acquittal on federal perjury charges in 2012.
Love him or hate him, believe him or doubt him, Roger Clemens changed baseball. Few pitchers have ever matched his intensity or competitiveness.
