Aroldis Chapman, all the split-fingers pitches before May 15, MLB 2021

Aroldis Chapman, the elite closer of the New York Yankees is well-known as 100 mph fastball and a hard slider. He has been seeking his 3rd pitch type and finally seems to succeed in adding a new pitch type. He threw the splitters 3 times (out of 199 ) last season, and this season 27 times by StatCast. This 100 mph closer is using the new pitch as a winning shot already.
