New York Yankees designated hitter Giancarlo Stanton powered the club’s offense against the Washington Nationals on Tuesday night, driving in five runs and launching a 451-foot home run to center field. The blast was part of a multihit performance that included a bases-clearing hit earlier in the game, giving the Yankees a lead they did not relinquish. Stanton’s latest display of power raises his season tally to 17 home runs in just 51 games, underscoring his importance to a Yankees lineup that has battled injuries for much of the year. The victory helps New York keep pace in the American League playoff race, while Washington continues a difficult road swing.
