No one has hit one out of Safeco during a game since the ballpark opened midway through the 1999 season.
For Judge, it was his 31st home run of the season, which leads the majors, and his first since the All-Star Game and Home Run Derby.
The New York Yankees' Baby Bombers have arrived in full force with Clint Frazier becoming the red-haired face of the second half of the 2017 crop.
Rangers 4, Rays 3, 10 Inns.: Elvis Andrus homered early and snapped a 10th-inning tie with a two-out infield single that gave struggling Texas a comeback win.
Sabathia, who had another quality start for the yanks, tried to show Judge in the dugout where his home run traveled.

Judge's long homer left fans buzzing and there were more than a smattering of boos when he was walked on a 3-2 pitch by reliever Emilio Pagan in the seventh. He allowed eight hits, but was outstanding when in trouble.
NY added to its advantage in the fifth, as Gardner and Sanchez singled with one out before Judge launched his homer to left, giving the Yankees a 5-1 lead. He walked three and struck out five.
The suggestion that the Home Run Derby may have messed with his swing - something has not seemed to trouble Cody Bellinger and Miguel Sano, whom Judge vanquished in the semifinals and finals of the derby - was dismissed by Judge.
