BOSTON — Joe Torre was back at Fenway Park on Friday night for Red Sox-Yankees, so just for old times’ sake, why not have a little drama between the two rivals? 

What’s become a mostly docile matchup in the AL East got some heat in the bottom of the fifth of a 6-1 Red Sox win, when Willson Contreras jawed at Will Warren as he headed to first base following a walk.

Warren, whose second pitch of the at-bat was up and in to Contreras — clearly crowding the plate — said some words back to Contreras and the benches cleared. 

After Contreras homered and had an RBI single off Warren earlier in the game, Contreras flipped his bat after Warren walked him on a 3-2 pitch that was close to Contreras’ elbow. 

Contreras continued to shout at the right-hander once he got to the bag, with first baseman Paul Goldschmidt looking to calm the situation. 

No punches were thrown and no one was ejected, but warnings were issued. 

Warren got Jarren Duran to ground out to end the inning. 

“It’s part of the game,” Contreras said of the incident. “Nothing happened. It looks worse when everybody comes out.” 

Warren didn’t have much to add. 

“Trying to make a pitch up and in,’’ Warren said. “That’s it.” 

Neither participant in the back-and-forth would divulge what was said. 

“I’m making a pitch, being competitive,’’ Warren said. “He said something, so I said something back. I’m just trying to make a pitch.” 

But Warren clearly wasn’t pleased with Contreras’ behavior at the plate, saying the slugger was “playing games in the [batters’] box.” 

Aaron Boone said it’s what Contreras is known for. 

“I think that’s what he does a lot,’’ the manager said. “His arms hang over the plate, so I don’t know where we’re supposed to go [with pitches]. I think there’s probably a method to what he’s doing. He probably wants that. But obviously, nothing’s going on. We probably needed to do a better job of getting the ball in on him tonight and didn’t. The warnings and the barking seemed kind of ridiculous.” 

Boone has a point, as only Starling Marte has been hit more times in his career than Contreras among active players. 

In April, drilled by Milwaukee’s Brandon Woodruff, Contreras said, “Next time they hit me, I’m going to take one of them out. That’s a message.” 

Woodruff laughed off the controversy, saying Contreras was “trying to get his side fired up, which is fine.”

Contreras was a menace to the Yankees all night, as he singled in a run in the first and homered to left in the third before the walk. 

The Yankees, losers of six of nine, have bigger concerns than any antics by Contreras as they try to right themselves against the last-place Red Sox.
