Da Costa kept Vandoorne at arm’s-length in the latter stages of a frenetic second race at the Brooklyn Street Circuit in Red Hook, where a flurry of late yellow flags reduced the Belgian's opportunity to mount a late pass.
A pile-up at Turn 6 on the antepenultimate lap, which involved Jean-Eric Vergne, Lucas di Grassi and Oliver Askew, left the Andretti driver stranded on the corner exit as di Grassi stopped further up the road on the exit of Turn 10, limiting Vandoorne's passing zones to Turn 1.
