Everyone has always known Jarren Duran can run, and at his best he’s the kind of guy who can spray doubles all over the park and wreak havoc whenever he gets on base.

But lately he’s shown a little pop in his bat as well.

Tuesday night the Red Sox outfielder hit his 20th home run of the season, a career-high that made him one of only four players in MLB who have recorded 20 homers and 30 stolen bases this season. He is also just the third Red Sox player to record a 20-30 season in franchise history, the others being Jacoby Ellsbury in 2011 (32-39) and Mookie Betts in 2018 (32-30).

He’s particularly found his power stroke lately. Entering Wednesday Duran had hit five home runs in his prior 11 games.

Red Sox manager Alex Cora said he’s not surprised to see Duran start popping the ball out of the yard more often.

“It’s the evolution of the hitter,” Cora said. “Jose Ramirez used to hit 50 doubles and 20 homers and now he hits 40 homers, you learn to hit the ball out of the ballpark, that’s the last thing that comes in the evolution of a player.”

The increased power output is perhaps the most surprising and encouraging aspect of what has been an extraordinarily successful season on the field. Duran recently became the first player in MLB history to record 10 triples, 20 home runs, 30 stolen bases and 40 doubles in a season, and he’s on pace to become just the eighth position player in franchise history to reach 9.0 wins above replacement.

Though Duran isn’t one to focus on his accomplishments, he acknowledged that he’s enjoyed being able to use his power to help the team, though he hasn’t decided whether he prefers home runs to stolen bases.

“Honestly I don’t I know,” Duran said. “I think they’re both equal, stealing is getting into position for the guys and hitting a home run and getting some RBIs for the team are probably two of the most important things.”

Duran likely won’t ever morph into a power-first player, and the best version of the 27-year-old outfielder is still one who uses his legs to pressure opposing defenses. Cora said he doesn’t want Duran to ever sell out for power, but that his growth as a hitter has made him much more dangerous.

Duran feels similarly, saying he’s always been “kind of that crazy player that runs around and uses my legs a lot.” One way he can do that still is by pushing for 40 stolen bases, which would make him the first Red Sox player ever to record a 20-40 season.

It would also give him a little bit of leverage on his outfield coach, Kyle Hudson.

“It would be cool to get to 40 so I could chirp Huddy a little bit, because Huddy is always telling me I need to run,” Duran said. “If I can get to 40 maybe he’ll go easy on me, but that would be awesome to get to 40.”
