After being called up by JGR to replace Denny Hamlin for the weekend, Ryan Truex finished his first session in the No. 11 Toyota 36th-fastest with a speed of 90.946 mph.
As the learning process got underway, the 15-turn, 2.42-mile Mexico City circuit proved to be tricky for the drivers. Turn 4 was one of the most challenging spots as Cindric missed his braking point and Noah Gragson contacted the wall in the same area. Others had trouble slowing their cars down in time to make the corner.
Cup Series drivers get back on track Saturday at 2:05 p.m. ET for qualifying (Prime Video, MRN Radio, SiriusXM NASCAR Radio).
