Markus Lynn “Mookie” Betts (born October 7, 1992) is an American professional baseball right fielder for the Los Angeles Dodgers of Major League Baseball (MLB).
He previously played for the Boston Red Sox. In 2018, while with the Red Sox, he became the first player in MLB history to win the Most Valuable Player, Silver Slugger, Gold Glove, batting title, and World Series in the same season.
Betts was drafted by the Red Sox in 2011, and made his MLB debut in the 2014 season, splitting time between second base and the outfield. He became the Red Sox center fielder in 2014, before moving to right field in 2016.
As a relatively short natural second baseman with a high contact rate and a high level of production when pulling the ball, Betts has been compared to former Red Sox teammate Dustin Pedroia.
Betts is also a professional tenpin bowler for the Professional Bowlers Association (PBA). He bowled a perfect game in the World Series of Bowling in 2017.
On February 10, 2020, the Red Sox traded Betts, David Price, and cash considerations to the Los Angeles Dodgers in exchange for Alex Verdugo, Connor Wong, and Jeter Downs.
On July 22, the Dodgers signed Betts to a 12-year contract extension, through the 2032 season. The deal was worth $365 million and also included a $65 million signing bonus, making it the richest contract in Dodgers history, and the third-richest contract in the history of North American sports.
Betts began seeing his long-term girlfriend, Brianna Hammonds, in high school. In November 2018, the couple had their first child, a girl. Betts and Hammonds announced their engagement in January 2021 and will marry in Palos Verdes, California on December 1, 2021. Their residence is in Franklin, Tennessee.
