Rickey Henderson, MLB's greatest base stealer and widely considered its greatest leadoff hitter, has died at the age of 65.

Henderson was a 10-time All-Star, spending the majority of his 25-year career with the Oakland Athletics.

Henderson, who would have turned 66 Christmas Day, was reportedly battling pneumonia.

Henderson is also the all-time leader in runs scored. He was named the American League MVP in 1990 after leading the AL with a 1.016 OPS, 65 stolen bases and 119 runs scored. 

He also played for the Yankees, Padres, Mets, Mariners, Red Sox, Blue Jays, Angels and Dodgers.

Henderson's wife, Pamela, confirmed her husband's death in a statement.

"A legend on and off the field, Rickey was a devoted son, dad, friend, grandfather, brother, uncle, and a truly humble soul. Rickey lived his life with integrity, and his love for baseball was paramount. Now, Rickey is at peace with the Lord, cherishing the extraordinary moments and achievements he leaves behind," Pamela said.

"For multiple generations of baseball fans, Rickey Henderson was the gold standard of base stealing and leadoff hitting. Rickey was one of the most accomplished and beloved Athletics of all-time," MLB Commissioner Rob Manfred said in a statement. 

"He also made an impact with many other clubs during a quarter-century career like no other. Rickey epitomized speed, power and entertainment in setting the tone at the top of the lineup. When we considered new rules for the game in recent years, we had the era of Rickey Henderson in mind. 

"Rickey earned universal respect, admiration and awe from sports fans. On behalf of Major League Baseball, I send my deepest condolences to Rickey’s family, his friends and former teammates, A’s fans and baseball fans everywhere."

Henderson won two World Series, one with the A's in 1989 and another with Toronto four years later.

Henderson became MLB's all-time stolen bases leader May 1, 1991, when he swiped third base in Oakland. He finished with 1,406 in his career, surpassing Lou Brock by nearly 500 bags. Henderson also retired with 2,295 runs scored, 50 more than Ty Cobb. His 3,055 hits are 27th all-time.

His 130 stolen bases in 1982 are the most in the live ball era. He and Vince Coleman are the only players since 1920 to have three seasons of at least 100 stolen bases. Henderson swiped 50-plus bags in 13 seasons, the most ever.

He made his debut in 1979 and hung up his cleats in 2003, accumulating 111.1 WAR in his 25 MLB seasons.

Two-time MLB All-Star pitcher Luis Severino and the Athletics have reached an agreement on a three-year contract, according to multiple reports.

The deal is reportedly worth $67 million, which would represent the most lucrative contract in the history of the typically budget-minded franchise. 

The deal exceeds the $66 million contract third baseman Eric Chavez signed for 2005-10. 

Severino had a strong 2024 campaign with the New York Mets, starting 31 games and posting a 3.91 ERA. He also struck out 161 batters in what became his first full MLB season since 2018. Severino has battled a number of injuries over the past five years.

Severino made his big league debut with the New York Yankees in 2015.

It didn't take long for the veteran right-hander to find success at the MLB level. He recorded 230 strikeouts and was named to the All-Star team in 2017, his first full season in a big league rotation.

Severino, who turns 31 Feb. 20, was a free agent for the second straight offseason after going 11-7 in his only season with the Mets. He left the Yankees last offseason to sign a one-year deal with the Mets guaranteeing $13 million, and he earned an additional $2 million in performance bonuses.

Severino is 65-44 with a 3.81 ERA in 156 starts and 16 relief appearances for the Yankees and Mets.

Severino turned down a $21.05 million qualifying offer from the Mets, who will receive an extra pick after the fourth round of next July’s amateur draft. The A's will forfeit their third-highest selection.

The Braves added that Carty left an indelible mark on the organization.

"While his on-field accomplishments will never be forgotten, his unforgettable smile and generous nature will be sorely missed," the team said in a statement.
