The Boston Red Sox have had great success on their current road trip.

The Sox are 4-0 heading into Friday’s matchup against the Seattle Mariners at Safeco Field. After completing a three-game sweep of the Baltimore Orioles, Boston squeaked by Seattle on Thursday with a 2-1 victory thanks in part to a solid outing from David Price.

The lefty has been strong on the hill for the Sox, much like the rest of the rotation, including Rick Porcello, who takes the bump in Friday’s contest.

Pitching coach Dana LeVangie and Porcello both talked about what’s been working for the starting rotation throughout the season.

Check out what they had to say in the “Red Sox First Pitch” video above, presented by Men’s Wearhouse.
