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.
Joel Zumaya: 104.8 MPH. Joel Zumaya was the hardest thrower in the game during the 2006 season. His 104.8 MPH pitch while closing for the Tigers is proof of that, and one of the fastest pitches EVER recorded in a pro-game.
