Swimming: Five-time Olympic champion Katie Ledecky of Bethesda signed her first endorsement deal since turning pro, partnering with swimwear company TYR. Ledecky made the announcement Friday, before competing in the Santa Clara, Calif., meet, which is expected to be her last event before U.S. nationals in July. Terms were not released, the company is calling the deal "the most lucrative partnership in the history of the swim industry." The move means Ledecky has secured what should be one of her biggest sponsors through the 2020 Tokyo Olympics and locks in the swim gear that she'll compete in as she takes aim at matching her medal haul from the 2016 Games in Rio de Janeiro. Ledecky announced in March after her sophomore season at Stanford that she was turning pro. She competed last month in Indianapolis wearing the gear of multiple companies before apparently settling on TYR, which has sponsored the U.S. team since 2013.
