NEW YORK — Jazz Chisholm Jr. hit a game-ending infield single with one out in the 11th inning and the New York Yankees outlasted the Kansas City Royals for a 4-3 victory Wednesday night.
Juan Soto launched a go-ahead homer in the sixth for the Yankees, who increased their advantage in the AL East to 1 1/2 games over Baltimore. New York has held the lead since Aug. 21 but hasn't led by more than two games during that stretch.
Shortly before Chisholm came through, the Orioles lost 5-3 in 10 innings at Fenway Park when Tyler O'Neill hit a walk-off homer for Boston.
Chisholm came up with runners on first and third after Kris Bubic (0-1) intentionally walked Aaron Judge following a groundout by Soto that sent automatic runner Jon Berti from second base to third.
With the infield playing in, Judge advanced to second on defensive indifference and Chisolm slapped a 2-1 slider toward shortstop. Bobby Witt Jr. made a diving stop on his backhand, but an off-balance throw from his knees was wide of the plate. Berti, who was pinch running, scored easily with a headfirst slide.
''Honestly, I was looking for a pitch that I could get through a hole or get to the outfield to score anybody on third base,'' Chisholm said. ''I was willing to pass the baton if I didn't get a pitch to hit.''
Chisholm batted cleanup for the second time since being acquired from the Miami Marlins on July 27. It was his first career walk-off hit and he was doused in water during the celebration while getting mobbed by teammates near second base.
Luke Weaver (5-3) struck out three in 1 2/3 hitless innings for the win.
