Manny Machado homered twice and drove in five runs, and Jackson Merrill and Brett Sullivan also went deep to carry the San Diego Padres to their second straight lopsided victory over the Boston Red Sox, 11-1 on Saturday.
It was the fifth straight win and ninth in 10 games for surging San Diego (46-41), which improved to a season-high five games over .500.
Jarren Duran hit a solo homer for the Red Sox, who lost their third straight.
Machado recorded his 40th career multihomer game, hitting a two-run drive completely out of Fenway Park in the third inning and a three-run shot to center during a six-run fifth.
When he rounded the bases after his second homer that made it 8-0, chants of “Manny! Manny!” echoed around Fenway from the many Padres fans.
“Yeah, I heard it coming in. A lot of Padres fans here,” he said, breaking into a smile. “It’s kind of weird to see it in Boston. I played here quite a bit and it’s kind of tough. … It was great to see a lot of yellow out there and hearing myself and the (Ha-Seong) Kim chants and the Jackson chants.”
