On May 1, 1991, Rickey Henderson of the Oakland Athletics stole his 939th base, surpassing Lou Brock's all-time record for stolen bases in Major League Baseball (MLB) history. The historic moment occurred during a game against the New York Yankees at the Oakland-Alameda County Coliseum.

Henderson, known for his incredible speed and baserunning skills, had been chasing Brock's record for years. As he stepped up to the plate in the fourth inning, the crowd buzzed with anticipation. Henderson drew a walk, setting the stage for his record-breaking attempt.

As Yankees pitcher Tim Leary delivered the pitch, Henderson took off for second base. Yankees catcher Matt Nokes' throw was off-target, and Henderson slid safely into second, cementing his place in baseball history. The game was momentarily stopped as Henderson's teammates rushed onto the field to congratulate him, and the crowd erupted in a standing ovation.

Henderson would go on to steal a total of 1,406 bases in his career, a record that still stands today. His achievement on May 1, 1991, was a testament to his incredible talent, dedication, and longevity in the sport.

Rickey Henderson's legacy extends far beyond his stolen base record. He was a 10-time All-Star, won two World Series championships, and was named the American League MVP in 1990. His unique blend of power, speed, and on-base ability made him one of the most dynamic players in MLB history. Henderson was inducted into the Baseball Hall of Fame in 2009, cementing his status as one of the greatest players to ever step onto the diamond.
