The Jazz Age is in full swing at Yankee Stadium. Whether with his bat, his glove, his arm or his smile, Jazz Chisholm Jr. is energizing the New York Yankees and their fans. Chisholm hit a second-inning, go-ahead homer and a bases-loaded triple while making three sparkling defensive plays at third base in a 12-5 romp over the Athletics. Chisholm is batting .318 with six homers, 18 RBIs and four stolen bases since returning from strained right oblique on June 3, raising his season totals to .242 with 13 homers, 35 and 10 steals in 53 games.
