Cam Schlittler pitched another playoff gem against the Red Sox as the Yankees opened their AL Wild Card Series rematch with a 9-0 victory.
Ben Rice burned their hometown team with a late grand slam and six RBIs in the same game.
The Yankees' 9-0 win marked a dominant start to the series against their longtime rivals.
Schlittler's performance continued his strong postseason track record versus Boston.
Rice's grand slam came late in the game and accounted for six of New York's nine runs.
The shutout victory highlighted the Yankees' early advantage in pitching and timely hitting.
Red Sox offensive struggles were evident as they failed to score against Schlittler and the Yankees' bullpen.
The result sets up a challenging path for Boston in Game 2, especially with lineup uncertainty.
It remains unclear whether Red Sox outfielder Roman Anthony will be available for Game 2 after exiting early with a hand injury.
Anthony's injury affects the same hand that previously sidelined him for nearly four months.
His potential absence adds to Boston's challenges in trying to rebound from the lopsided loss.
The Yankees, meanwhile, look to build on their strong start as the series shifts focus to Game 2.
Both teams now prepare for the next contest with clear implications from Game 1's outcome.
