BOSTON -- J.D. Martinez has gone from a power outage to a power surge, and the Red Sox are loving every bit of it.

The star slugger mashed his fourth homer in the past three games on Wednesday night, a two-run shot into Boston’s bullpen in right-center field in the bottom of the third while helping his Red Sox to a 6-5 victory over the Rockies in 10 innings.

It was also Martinez’s fifth long ball in the past seven games. This outburst has come directly on the heels of Martinez going 62 at-bats and 15 games without a homer, his longest drought since 2014.

This latest smash against Rockies starter German Marquez was vintage Martinez, as he turned perfectly on an 0-1 slider and laced it to the opposite field to give the Red Sox a 5-0 lead.

“For a while there, I think he hit a few fly balls early in the season that in the summer, they're gone," said Red Sox manager Alex Cora. "Lately, he's been more disciplined in the strike zone. Obviously, he's getting pitches in his zone, and he's not missing them. At the same time, he's working the count and getting to those counts to take advantage of that.”

Martinez now has nine homers on the season. But more than the homers, Martinez takes pride in his approach, which has been contagious in his year-plus with the Red Sox.

“I try to go out there every day and be an example to everyone in here and just try to be an example on the field -- take really, really tough at-bats, not give away at-bats, not give away outs, make the pitchers work for every out, every pitch," Martinez said. "That's something I take pride in."
