[47] After leading both practice sessions at Barber Motorsports Park, Abel continued his pace in qualifying to take pole position.
[48] The top two remained unchanged at the start and through an early caution period called when Abel's teammate Yuven Sundaramoorthy stopped on track.
[50] Having taken his and his teams' maiden win at Mid-Ohio, Abel immediately doubled up at the next race: He made a great start, leaving Collet and Foster to fight over second, and went unchallenged until the finish.
Two more late cautions allowed Foster to recover to seventh, while his teammate Jamie Chadwick avoided the carnage to claim third.
[51] The second race at Indianapolis began four cars wide into the first turn, with Collet taking the lead from Abel and Foster and Chadwick slotting in behind.

An early safety car caused by HMD's Reece Gold retiring in the gravel also offered no opportunity for Collet to trouble Foster.
He limped across the line on three wheels, allowing Abel back into third to deny Foster the championship lead, with the pair now equal on points.
[58] The second race of the weekend proceeded in very similar fashion, as Foster's pace continued to be a step above the rest of the field.
A spin by Hedge caused a caution period halfway through the race, but Foster controlled the restart and went on to complete his weekend sweep.
[59] Mid-Ohio hosted round ten, and a repaving meant Collet not only took pole position, but also set a new lap record.
