The only thing Barry Wanser failed to do on Sunday afternoon at Nashville Speedway was hold back the tears that were welling in his eyes.

He’d just clinched the third NTT IndyCar Series championship in four seasons with Alex Palou and the No. 10 Chip Ganassi Racing Honda entry he leads. One year ago, when Palou and the No. 10 crew were celebrating their second championship at Portland International Raceway, Wanser was missing. More accurately, he was missing from the event and the joyous revelry because he was at home in Indiana, facing the scariest challenge of his life.

A few weeks earlier, cancer was found in his mouth and tongue, and with his driver on the cusp of winning a second IndyCar title, Wanser wanted to wait until the IndyCar championship was completed before tending to his own needs. Thankfully, his doctor interceded; Wanser informed the team that his season was over. Battling cancer needed to start immediately, and that meant skipping Portland and the finale at Laguna Seca to perform surgery and commence chemotherapy.
