What happened: Ryo Hirakawa rolled out onto the Autódromo Hermanos Rodríguez circuit at the start of Free Practice 3 for Haas. The outing marks Hirakawa's first track time of Saturday after Haas named the reserve driver to replace Esteban Ocon for the remainder of the Mexico City Grand Prix weekend.

Why it matters: The 60-minute session serves as Hirakawa's sole preparation before Saturday afternoon qualifying alongside teammate Oliver Bearman. Haas made the driver change following FP2, giving the Japanese driver an unexpected Grand Prix debut opportunity while Ocon sits out the rest of the event.

What to watch: Qualifying for the Mexico City Grand Prix takes place later Saturday afternoon following the conclusion of FP3.
