During the June race at Michigan International Speedway, while racing near the back of the field, Mears wrecked his Team Red Bull teammate, Scott Speed. Speed went on to finish 28th and Mears finished 36th. Following the race, Speed was critical of the incident, and Mears was soon replaced by Reed Sorenson. Mears returned to TBR beginning with the Lenox Industrial Tools 301 at New Hampshire Motor Speedway on June 27, 2010, where he finished 29th, only two laps down.
