VIDEO: JD Martinez Unleashes 3-Run Homer to Open the Scoring at Petco Park

JD Martinez wasn't going to waste a whole bunch of time tonight on the road in San Diego. In the top of the first inning, the Red Sox slugger let loose on this Chris Paddack fastball and made the Padres pay.

The sun's still out, but not for long. If the Boston boys have their way, it will be a dark Friday night for the hometown Padres.

Martinez has been a bright spot for the defending champs this season, who have suffered through some uncharacteristic struggles-- mostly up and down their pitching staff. He'll need to keep the mojo working if the playoffs are to become a reality in the relentless American League. So far, so good in SoCal.
