The Yankees acquired Gold Glove-winning center fielder Harrison Bader from the St. Louis Cardinals for left-hander Jordan Montgomery ahead of Tuesday’s trade deadline, a surprising deal aimed at improving defense. A speedy 28-year-old from Bronxville, New York, Bader has not played since June 26 because of plantar fasciitis in his right foot. When he returns, he likely would play share center field with newly acquired Andrew Benintendi in a move that would put Aaron Judge back in right and see Aaron Hicks and Benintendi share time in left, with Giancarlo Stanton as the designated hitter.
