On April 29th in sports history, one significant event took place in 1986 when Roger Clemens, the legendary pitcher for the Boston Red Sox, set a new Major League Baseball record by striking out 20 batters in a single nine-inning game. This incredible feat occurred during a game against the Seattle Mariners at Fenway Park.

Clemens, known as "The Rocket" for his powerful fastball, was in top form that night. He dominated the Mariners' lineup, striking out almost every batter he faced. The 23-year-old right-hander was untouchable, allowing only three hits and walking none in a complete game shutout.

The previous record for strikeouts in a nine-inning game was 19, shared by Steve Carlton, Tom Seaver, and Nolan Ryan. Clemens surpassed that mark with his 20th strikeout in the ninth inning when he fanned Phil Bradley to end the game. The final score was 3-1 in favor of the Red Sox.

Clemens' performance was so impressive that even the Mariners' players couldn't help but appreciate his skill. After the game, Mariners designated hitter Gorman Thomas said, "I've never seen anything like it. He was awesome."

The 20-strikeout game was just one of many highlights in Clemens' illustrious career. He went on to win seven Cy Young Awards, an MVP, and two World Series championships. However, that night at Fenway Park remains one of the most memorable moments in his career and a remarkable achievement in sports history.
