Yankees star Aroldis Chapman’s muscles look ridiculous in new photo

This might help explain Aroldis Chapman’s signature fastball.

The star Yankees closer looked swole as ever in a picture he shared to Instagram on Saturday, showing himself on the far right alongside a few friends playing dominoes.

Chapman, whose 105.1-mph fastball was the fastest pitch recorded by MLB, has spent some of baseball’s coronavirus-induced break bulking up, as shown by another social-media photo of the 32-year-old power-lifting two weeks ago.

So it goes for Chapman, long regarded as one of MLB’s best athletes — and not just because of his hulk-like muscles.

A baseball insider once told The Post’s George King that the 6-foot-4, 215-pound Chapman beat speedster center fielder Billy Hamilton, who stands 6 feet and 160 pounds, in a 100-yard dash while the two were with the Cincinnati Reds in the mid-2010s. In 2017, YES Network shared video of Chapman doing impressive 1,000-pound leg presses.

While Chapman continues to stay fit, it remains to be seen when, or if, baseball will return for the 2020 season. The virus has infected two Yankees minor leaguers and caused the suspensions of multiple professional sports leagues across the world.
