David Ortiz homered while Hanley Ramirez and Xander Bogaerts added two-run doubles to lead the Boston Red Sox to a 7-2 victory over the Detroit Tigers on Friday night.

Boston improved to 2-2 on its eight-game trip.

J.D. Martinez hit his 30th homer for the Tigers.

Daniel Norris (2-2) gave up three hits in a 39-pitch first inning, including Ramirez's double that staked Joe Kelly (4-6) to an early lead.

Ortiz made it 4-0 in the third with a drive to deep right field, his 22nd of the season. It was his 20th homer at Comerica Park, the most by a visiting player in the 15 seasons since it opened. He averages a home run almost every 10 at-bats here in his career.

Norris, one of three left-handers acquired July 30 in a trade that sent All-Star David Price to Toronto, allowed four hits and a run in 7 1-3 innings at Baltimore on Sunday in his Tigers' debut.

His first game before his new hometown fans lasted just 3 1-3 innings. He allowed five runs and nine hits with three strikeouts.

Martinez made it 5-2 in the fourth with a two-run homer into the Red Sox bullpen but Bogaerts restored Kelly's five-run lead with a sixth-inning double off reliever Buck Farmer.

The Tigers got runners to second and third with one out in the sixth to chase Kelly but reliever Robbie Ross stranded them by striking out Rajai Davis and getting Nick Castellanos to ground out.

Boston's Justin Masterson loaded the bases with one out in the bottom of the ninth but Koji Uehara killed any hopes of a rally and earned his 25th save in 27 chances by striking out Jose Iglesias and getting Ian Kinsler to meekly ground out.

Kelly, in his first career start against Detroit, allowed seven hits and struck out seven — including a stretch of five straight — with two walks.
