Javier Báez took a swing.
On a 2-2 fastball from Boston Red Sox reliever Ryan Brasier, the Detroit Tigers' new shortstop deposited the ball into the stands beyond the left-field wall, and beyond the bullpen, in the eighth inning.
The two-run home run from Báez, who signed a six-year, $140 million contract this offseason, traveled 396 feet and provided a 3-1 win for the Tigers in Monday's series opener against the Red Sox at Comerica Park.
Left-handed closer Gregory Soto pitched the ninth inning and notched his first save of the season.
The Báez blast snapped a 1-all tie.
