PHILADELPHIA — Newcomer Hanley Ramirez and Dustin Pedroia each hit two home runs, Clay Buchholz threw three-hit ball over seven innings and the Boston Red Sox beat the Philadelphia Phillies, 8-0, in the season opener Monday.

Buchholz (1-0) showed the Red Sox they don’t need to trade for any ace – namely Cole Hamels (0-1). Buchholz struck out nine and pitched like the guy who went 12-1 in 2013.

Ramirez made quite an impression in his first game since he signed an $88 million, four-year contract with Boston. He hit a solo homer in the fifth and a grand slam off Jake Diekman in the ninth.

Hamels gave up five hits in five innings, striking out six. He allowed four homers in a game for just the second time in his career.

Mookie Betts also homered for Boston.

The Red Sox have been considered front-runners to land Hamels since the rebuilding Phillies made the 2008 World Series MVP available. But Boston isn’t going to trade its best prospects for this version of Hamels.

Red Sox slugger David Ortiz kept both feet in the batter’s box for nearly every pitch during his four at-bats, going 0 for 4 with three strikeouts. Ortiz made it clear in spring training that he doesn’t like baseball’s new pace-of-play rules, but he adhered to them in his first game. The only time he stepped out was after fouling a ball off his foot.

The revamped Red Sox spent $183 million on Ramirez and Pablo Sandoval, hoping their offense can lead them to another worst-to-first season like they had when they won the World Series in 2013.

Sandoval was 0 for 5 with two strikeouts.

Buchholz didn’t allow a hit until Ryan Howard lined an 0-2 pitch for a double with two outs in the fourth. Junichi Tazawa tossed a perfect eighth and Tommy Layne finished off the three-hitter.

Pedroia hit a towering drive out to left-center in the first inning to give the Red Sox a 1-0 lead. Betts lined one out to left leading off the third.

In the fifth, Pedroia connected again for his first multihomer game since Sept. 13, 2011, against Toronto. One out later, Ramirez hit a deep drive to left-center.

Pedroia snuffed Philadelphia’s rally in the seventh inning. After consecutive one-out hits, Pedroia made an excellent play at second base on Cody Asche’s hard one-hopper and turned it into a fielder’s choice. Buchholz then struck out Freddy Galvis to end the inning.
