Autographs of Klay Thompson
Klay Alexander Thompson (born February 8, 1990) is an American professional basketball player for the Dallas Mavericks of the National Basketball Association (NBA). He played his first 13 seasons with the Golden State Warriors, where Thompson was part of the "Splash Brothers." He is widely regarded as one of the best three-point shooters of all time. Thompson is a four-time NBA champion, a five-time NBA All-Star, a two-time All-NBA Third Team honoree, and was once named to the NBA All-Defensive Second Team. He has also won gold medals with the United States national team on their 2014 World Cup team and 2016 Olympic team.
The son of former NBA player Mychal Thompson and brother of NBA player Mychel Thompson and Major League Baseball player Trayce Thompson, Klay Thompson played college basketball for three seasons with the Washington State Cougars, where he was a two-time first-team all-conference selection in the Pac-10 (now Pac-12). Thompson was selected in the first round of the 2011 NBA draft by Golden State with the 11th overall pick. In 2014, he and teammate Stephen Curry set a then-NBA record with 484 combined three-pointers in a season (a record they broke the following season with 525 and again in the 2015–16 season with 678), earning the pair the nickname of "the Splash Brothers." In 2015, Thompson helped lead the Warriors to their first NBA championship since 1975. The following season, he helped the Warriors win a record 73 games. The team advanced to the NBA Finals that season, losing to the Cleveland Cavaliers in seven games. Thompson and the Warriors avenged their 2016 finals loss, winning two more titles in 2017 and 2018. He also helped the Warriors reach their fifth straight Finals in 2019, where he suffered a torn ACL late in the series. After missing over two and a half years of play due to injury, Thompson returned in the middle of the 2021–22 season, where he won his fourth title in 2022.
Thompson was born in Los Angeles to Julie and Mychal Thompson. His mother was a volleyball player in college for the University of Portland and University of San Francisco, while his father was the first overall pick of the 1978 NBA draft. When Thompson was two, he and his family moved to Lake Oswego, Oregon, where Thompson was childhood friends and Little League teammates with fellow future NBA star Kevin Love. Thompson and his brothers were raised there as devout Catholics and have Bahamian ancestry through her father.
