The morning session was largely played out in front of sparse crowds after logistical issues prevented thousands of fans from getting to the course in time for the opening tee shots at 07:05 (12:05 BST).
The LPGA apologised for the disruption, which saw some fans take more than two hours to reach the venue by bus from the car park.
It led to the usually bouncing stand around the first tee being half-empty with a slightly muted atmosphere as the DJ’s blaring soundtrack largely drowned out those lucky enough to have made it.
All three of the American victories were by 3&2 scorelines – and all three were down to American dominance on the back nine.
Korda and Corpuz won three successive holes from the 14th, while behind them, Zhang and Coughlin were involved in a tight tussle with Celine Boutier and Albane Valenzuela.
The US pair twice went one up, only to see Europe immediately respond.
However, a run of three successive wins from the 12th gave the American’s daylight and when Switzerland’s Valenzuela was too aggressive with a birdie putt on the 16th, the hole was halved in pars, which was enough for a second red point.
Spain’s Carlota Ciganda and Sweden’s Linn Grant were always behind after losing the first hole to Lilia Vu and Schmelzel. But the Americans only pulled clear when they took the 12th and 13th holes to go three ahead. Ciganda holed a putt on the 14th to claw one back but could not repeat that feat on the 15th and a third red point was confirmed on the next.
Europe desperately needed the final match out on the course to stay blue. Stark and Pedersen blazed to a quick start but were left holding on down the stretch.
Ally Ewing and Jennifer Kupcho closed to two down with four to play and that was down to one when Europe lost the 15th.
But the Scandinavian pair held their nerve, with Stark firing her approach to the last to within three feet, which was enough to seal an important point.
As holders, Europe need 14 of the 28 available points to lift the Solheim Cup for a record fourth successive time, while the US need 14½ to earn a first win since 2017.
