Corey Heim wins the NASCAR Cup Series race at Naval Base Coronado in San Diego, taking first place in the inaugural event at the venue. Multiple outlets report that Heim outduels teammate Tyler Reddick to earn his first-ever Cup Series win. Coverage notes that Heim enters the race as a part-time driver and is in only his 13th career Cup start, with reporters also pointing to a transition toward a full-time Cup ride beginning next year. Several accounts describe a difficult race for Heim, including contact and spins or impacts early in the event that damage his car and tires, yet he continues and maintains the lead at the end. One source characterizes the timing of the win as faster than expected based on Heim’s longer-term prospects, reflecting that he was viewed as a major potential contender once he had a full-time opportunity. Across reports, the key result is consistent: Heim finishes ahead of Tyler Reddick to claim the inaugural San Diego Cup victory.
