The Red Sox lost to the Royals on Sunday night (KC 10, BOS 4), moving their record to 72-58 on the season. Boston is two games back of the Blue Jays for first place in the AL East, and they have a one-game lead over the Orioles for the second wild card spot with five weeks to play.

That 72-58 record means there are only 32 regular season games left in David Ortiz‘s playing career. He’s planning to retire after the season despite still being very productive. He clobbered his 31st home run of the season Sunday night. Check it out:

That was not a wall-scraper. Ortiz hit that ball out to the deepest part of the ballpark. Big Papi is hitting .319/.407/.633 (116 OPS+) with 31 homers and 101 RBI in 2016. He leads all of baseball in doubles (41), slugging percentage (.633), and OPS (1.040).

And yet, despite all that production, Ortiz says he’s a “little worn out.” Here’s what he told the Associated Press on Sunday:

“Very busy. Kind of tired of it, a little worn out,” the Red Sox star told The Associated Press before the Kansas City Royals beat the Red Sox 10-4 on Sunday night.

“My job is kind of tiring,” he said. “Adding more things to it is a lot. … I’m really busy and not getting to enjoy things.”

If Ortiz is indeed worn out, it’s not showing in his numbers. His worst month this season was the .903 OPS he put up in July. Only 22 players have .903+ OPS for the season overall, yet that was Ortiz’s worst month. Crazy.

Red Sox manager John Farrell has made sure to give Ortiz, who will play the entire season at age 40, regular rest throughout the season. It’s not often he plays more than six or seven games in a row, plus he’s often lifted for pinch-runners and even pinch-hitters in blowouts.

The Red Sox have gotten much better work from their starting pitchers of late, though make no mistake, their strength is their offense. They lead all of baseball with 704 runs scored and Ortiz is a big part of that. Getting worn down is inevitable, even as a DH. Managing that fatigue in September will one of Farrell’s most important responsibilities.
