As far as home runs go, the 2018 Yankees lived up to the hype. The set a new Major League record with 267 homers, and they did that despite Aaron Judge missing close to the two months, Giancarlo Stanton not having a typical Giancarlo Stanton year, and Gary Sanchez being either hurt or ineffective all year. This club would’ve shattered the previous homer record (264 by the 1997 Mariners) with everyone at full strength.
As far as home run distance goes, the 2018 Yankees lagged behind the 2017 Yankees and the rest of the league. Part of it is the ball seemingly being de-juiced — there were 5,585 homers hit this season after a record 6,105 last season — and part of it is the aforementioned injuries and ineffectiveness.
