Potomac sophomore Kharya Brown is quickly becoming one of the state\'s top sprinters after performances such as last Saturday\'s 55 meter dash win at the Montgomery Invitational. In the meet, Brown won in a state best time of 7.24 to earn athlete of the week honors. Brown, who last year ran for Gar-Field as a freshman but transferred over to Potomac during the off-season, figures to be a favorite in the battle for the state crown in the event.
