Michael Costello earned his second-career win in Formula 4 United States Championship Powered by Honda (F4 U.S.) on Saturday morning at Mid-Ohio Sports Car Course. Driving the No. 19 Jay Howard Driver Development (JHDD) / CSU One Cure / Lucas Oil / LHP Ligier JS F4, Costello endured a race filled with changing track conditions to take home the trophy.

After a rain-filled afternoon Friday, qualifying was cancelled and the field lined up by championship point standings to start the race. Patrick Woods-Toth (No. 27 Crosslink-Kiwi Motorsport Ligier JS F4) led the way, with everyone on slick Hankook tires. However, a pop-up rain shower during the formation lap led to several offs and forced the field back down pit road as cleanup ensued. Race director Scott Goodyear made the call for a mandatory switch to rain tires for all teams and called for a two-by-two rolling start.
