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.
The Guinness Book of World Records still acknowledges Nolan Ryan's 100.9-mph pitch in 1974 as the fastest ever recorded. Yet pitchers Joel Zumaya and Mark Wohlers have since thrown 104- and 103-mph fastballs, respectively, since Ryan's throw, but Guinness didn't certify the results from the guns used to measure them.
