A thrilling fourballs session was going the way of the Americans as they led in three matches deep into the back nine.
But Viktor Hovland, Jon Rahm and veteran Justin Rose ensured Europe won it 2-1/2 to 1-1/2, with three matches that went all the way to the 18th.
"That was my moment there on the 18th -- I've made us a lot of points but I haven't had many moments like that so that was immense," Rose, playing his sixth Ryder Cup, said.
Hovland was majestic as he and Aberg, the first Ryder Cup player not to contest a major, proved too hot for Homa and Harman to handle in match two.
Matt Fitzpatrick, playing with McIlroy, earned his first Ryder Cup point in stunning fashion with four birdies and an eagle in an early blitz that Morikawa and Schauffele never recovered from, losing 5&3.
