All-Star third baseman Rafael Devers, one of the top hitters in baseball, will reportedly be staying with the Boston Red Sox over the next decade plus.Multiple reports indicate that the Red Sox and Devers are in agreement on an 11-year, $331 million contract extension. Ken Rosenthal of The Athletic reports the deal includes a $20 million signing bonus.ESPN's Jeff Passan reports that the deal is not yet done since the physical process has not started, but that Devers is expected to remain in Boston in the end.The total contract value of $331 million ranks as the sixth-highest ever in Major League Baseball history and is more than 50% larger than the Red Sox's previous high contract by total value: the $217 million Boston agreed to pay starting pitcher David Price over seven years when they signed him in 2015.The 11-year length of the contract surpasses the eight-year, $160 million deal outfielder Manny Ramirez signed with the Red Sox in December 2000. Ramirez won two World Series titles with Boston (2004, 2007) and is a member of the Red Sox Hall of Fame.News of the mega contract extension comes one day after Devers and the Red Sox agreed on a $17.5 million contract for the 2023 season to avoid the salary arbitration process.Passan is reporting that the 11-year contract extension will start this year and extend through the 2033 season, when Devers will be 36 years old. The one-year, $17.5 million contract will be superseded by the long-term deal, according to Passan.Rosenthal initially reported the 11-year contract extension will begin in 2024, but later made the correction that it will start this year.Devers, 26, is coming off a season in which he was limited to 141 games by a right hamstring injury, batting .295 with 42 doubles, 27 home runs and 88 runs batted in.He was the American League's starting third baseman in each of the last two All-Star Games and has finished in the top 15 of AL Most Valuable Player voting in 2019 (12th), 2021 (11th) and 2022 (14th).Since the start of the 2019 season, Devers leads the major leagues with 149 doubles and 264 extra-base hits and leads the American League with 591 hits and 1,078 total bases.The Red Sox originally signed Devers as an international free agent out of the Dominican Republic in 2013, and he made his major league debut in July 2017.In 689 career games, Devers has a batting average of .283 with 187 doubles, 139 home runs and 455 RBI. He won an American League Silver Slugger award in 2021 and helped Boston win the World Series in 2018.The news of Devers agreeing to sign with Boston long term is great news for Red Sox fans, as it comes nearly a month after All-Star shortstop Xander Bogaerts — who played the first 10 seasons of his MLB career with the Red Sox — agreed to join the Sand Diego Padres on an 11-year, $280 million contract after Boston failed to agree to terms with him before and throughout the 2022 season.Several members of the Red Sox's 2018 championship team have chosen to sign elsewhere in free agency. While Bogaerts went to the Padres, designated hitter J.D. Martinez signed with the Los Angeles Dodgers while right-handed pitcher Nathan Eovaldi signed with the Texas Rangers.The Red Sox have signed All-Star closer Kenley Jansen and outfielder Masataka Yoshida, a star player in Japan’s Nippon Professional Baseball league. Boston has also reportedly agreed to sign All-Star infielder Justin Turner, formerly of the Dodgers, and two-time Cy Young Award winner Corey Kluber.
