Two-time Olympic champion Caster Semenya lost her appeal Wednesday against the International Association of Athletics Federations, whose rules are designed to reduce naturally high testosterone levels in some female runners.
Why it matters: The decision, announced by the Court of Arbitration for Sport, means that athletes like Semenya will be forced to reduce their natural levels of testosterone to run track events from 400m to the mile.
As baseball, like all sports, becomes more data-oriented and technology-driven, MLB hitting coaches are no longer required to have actually played in the big leagues.
Details: Instead, teams are looking for coaches who are well versed in how to use the new technologies available to them (hitting apps, machines) and leverage the data they produce.
