And he achieved a little bit of history with this #feat.
The 25-year-old received 28 first-place votes and two second-place votes to take home the hardware.
Cleveland third baseman Jose Ramirez was third with 208 points, and Red Sox designated hitter J.D. Martinez was next with one first and 198 points.
Milwaukee Brewers outfielder Christian Yelich is the National League's Most Valuable Player for 2018.
Betts, who just turned 26, was drafted by the Red Sox in the fifth round of the 2011 draft as a high schooler out of Tennessee.
Betts owns something approaching his own chapter of the Boston record book after just his fourth full season.
Betts hit a major league-leading.346 with 32 homers, 80 RBI and 30 stolen bases as the leadoff hitter for the Red Sox, who won a team-record 108 games and their fourth World Series title in 15 seasons.
Betts said he is ready to take the greater exposure the MVP and the Red Sox season will create and embrace it even more to become an ambassador for the game.

The President also said Pence's loyalty has been tested in many ways, and he couldn't be happier with his pick for Vice President.
"Right now I'm just focusing on the 2019 season coming up", he said.
Trout's run of MVP finishes is historically impressive.
Yelich won the first batting title in Brewers history with a.326 average.
Clearly, though, Yelich stood above the rest of the position-player field.
He was one of three finalists, beating out Cubs infielder Javier Baez and Rockies third baseman Nolan Arenado for the honor.
The only first-place vote Yelich didn't get went to New York Mets Cy Young Award victor Jacob deGrom.
Yelich almost pulled off a unanimous win after helping lead the Brew Crew to a stirring NL Central title.
Yelich, who was traded from the Miami Marlins to Milwaukee in January, almost won the first NL Triple Crown since Joe Medwick did so in 1937.
Milwaukee swept Colorado in the Division Series then lost to the Los Angeles Dodgers in a seven-game League Championship Series, falling one win short of its first World Series appearance since 2002. He also had 47 doubles, five triples, 129 runs and 80 RBIs, and his 1.078 OPS was second in Major League Baseball behind only Trout (1.088).
