There is an article on ESPN Rumor Central that reports Chapman hit 105mph on one of his fastballs last night. It was verified by at least two guns. All of the rest of his fastballs were 100-104mph.
Can you imagine guys like Cueto and Volquez blowing away people with their 95mph fastballs, and then Chapman can throw it 10mph faster? That's ridiculous. Compared to Chapman, it is like Cueto and Volquez are throwing slop up there.
What is the record for fastest recorded pitch?
