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.
Currently, Aroldis Chapman holds the record for the fastest recorded pitch in the history of major league baseball at a speed of 105.1 mph. He has also thrown a pitch that reached 106 mph in a different game, but this speed has been disputed, so the current record sits at 105.1 mph.
