We X-Rayed Some MLB Baseballs. Here’s What We Found.

On 6,105 occasions last season, a major leaguer walked to the plate and hammered a baseball over the outfield wall. The 2017 season broke the home run record that was set in 2000 — the peak of the steroid era — when players hit 5,693 homers, and it built upon the remarkable 5,610 that were hit in 2016. It was a stunning display of power that played out in every MLB park almost every night. And with spring training underway in Florida and Arizona, MLB’s power surge is showing no sign of letting up.
