Chisholm hit his 30th home run of the season on Friday night off Baltimore Orioles relief pitcher Dietrich Enns in the bottom of the seventh inning.
He joins New York Mets outfielder Juan Soto as the only two players in baseball to join the 30-30 club this season. Arizona Diamondbacks star Corbin Carroll needs just one more stolen base to join them.
Meanwhile, Pete Crow-Armstrong of the Chicago Cubs and Jose Ramirez of the Cleveland Guardians need one more home run.
Chisholm's 30 home runs, 77 RBI, and 56 walks are already career-highs for him, but he needs 11 more stolen bases to eclipse the 40 he put up last season.
The 27-year-old Bahamas native was slashing .242/.333/.479 heading into Friday's matchup as he continues to be one of the Yankees' best hitters this season.
Chisholm signed a one-year, $5.85 million deal with New York this past offseason and will undoubtedly receive a much bigger payday once the season is over.
New York (86-67) sit 3.0 games behind the Toronto Blue Jays for the American League East division lead, but currently hold the top Wild Card spot in the AL with eight games left in the regular season.
