Clayton Kershaw didn't take a break after closing out the Dodgers' Game 7 win over the Milwaukee Brewers in the NLCS late Saturday night.
On Sunday, less than a day after the win, he was seen in the Fenway Park bullpen going through his motions.
He'll likely be the starter for Game 1 of the World Series against the Red Sox on Tuesday night.
Kershaw started Game 1 and Game 5 of the NLCS. He has a 2.37 ERA in 19 innings this postseason.
The Red Sox beat the Astros in five games to make the World Series.
