The record-setting home run came against Kansas City Royals pitcher Trevor Cahill.
Many have stepped to the plate. None have hit 50 homers as a rookie.

The previous record had stood for 30 years, with Mark McGwire hitting 49 in 1987 for the Oakland Athletic.
Judge is also the fifth Yankee to top the mark. It had previously been done by Babe Ruth, Mickey Mantle, Roger Maris, and Alex Rodriguez. It’s the ninth time in team history that 50 home runs has been reached, with Ruth reaching the mark four times and Mantle doing so twice.
