New York Yankees manager Aaron Boone said his only regret from Friday night's loss to the Los Angeles Dodgers in Game 1 of the World Series was not putting Luke Weaver on the mound in the tenth inning.

"Do I send Weave out with the lead for the third up... in the tenth? That's the one that certainly I can make a case for in my head," Boone told reporters on Saturday when asked if he had made decisions he would like to take back in Game 1.

"Worry about, a little bit, that third up with them, and then where's that leave us, if that doesn't go according to plan... that's the one. But the other ones, no, I would double down on."

Weaver closed out the eighth inning and retired three batters in order in the ninth, but Boone turned to Jake Cousins and then Nestor Cortes for the tenth frame.

In his return from over a month sidelined due to an elbow injury, Cortes' second pitch was returned by the Dodgers' Freddie Freeman for a walk-off grand slam.

Weaver originally came into the game to face Mookie Betts with the tying run on third and just one out on the board. After Betts scored Shohei Ohtani on a sacrifice fly, Freeman hit a fly out to end the inning.

In the ninth, Weaver forced Teoscar Hernandez, Max Muncy and Enrique Hernandez into popouts and flyouts.

But Weaver had only pitched two full innings once this postseason, in the Yankees' Game 5 ALCS-clinching win over the Cleveland Guardians. Boone retired him after 1.2 frames to put Cousins on the mound in the tenth.

Cousins walked Gavin Lux with one out of the board, then allowed an infield single by Tommy Edman before he was taken out in favor of Cortes, who last pitched on Sept. 18 before suffering a UCL injury.

The Yankees held a one-run lead when Boone made the controversial decision to walk Betts, loading the bases with one out still remaining.

In the ninth inning, allowing an intentional walk had worked out for the Dodgers when they allowed Juan Soto on base before forcing Aaron Judge to pop out.

The same tactic did not work as well for the Yankees. Freeman hit his grand slam on Cortes' next pitch.

Weaver's reliability as a closer has been a key part of the Yankees' run to the World Series. He has recorded four saves in nine appearances, and outside his struggles in Game 3 of the ALCS has been consistently solid.

Given Boone's regrets from Game 1, the pressure could be on Weaver to close out Game 2 if the Yankees find themselves with a similar late lead on Saturday night in Los Angeles.
