Transgender is also an umbrella term: in addition to including people whose gender identity is the opposite of their assigned sex (trans men and trans women), it may include people who are not exclusively masculine or feminine (people who are genderqueer, e.g. bigender, pangender, genderfluid, or agender).
Chapman holds the record for the fastest recorded pitch speed in MLB history at 105.1 mph (169.1 km/h) as well as the Guinness World Record for fastest baseball pitch for a male.
Aroldis Chapman - 104 mph pitch in Sept. 2010. At the Reds vs. Brewers game on September 1, 2010, Aroldis Chapman threw a fastball clocked at 104mph, but it is believed he can go to 105. So i would say that the fastest pitcher of our time has got to be Aroldis Chapman.
