Mosack, 23, currently competes full-time for TeamSLR in the TA2 division but will make his Xfinity Series debut June 4 with Joe Gibbs Racing in the inaugural series race at Portland (Ore.) International Raceway.
Mosack’s No. 18 Toyota will be sponsored by Open Eyes, a global ministry co-founded by Frank Harrison, Chairman and CEO of Coca-Cola Consolidated, and his son James Harrison, who passed away while serving in Kenya in 2010. Mosack volunteered with the group in Africa during the summer of 2017, visiting Rwanda and Uganda.
