A European fightback was under way at Hazeltine as the reigning Ryder Cup champions looked to atone for a dismal morning session on Friday.
The United States, seeking a first triumph since 2008, spectacularly seized control of proceedings by completing a clean sweep of the opening foursomes.
However, as the afternoon fourball matches approached the turn, Europe were ahead in three out of four contests, having claimed some much-needed momentum.
Henrik Stenson and Justin Rose had been beaten 3 and 2 by Patrick Reed and Jordan Spieth in the morning, but the European pair were two up through eight holes in a rematch of the duel that started the event.
Reed and Spieth combined for birdies on each of the first three holes, but their opponents refused to buckle and held a handy cushion when Stenson almost aced the eighth - the resulting birdie enough to win a second hole in succession.
In match two, the all-Spanish pairing of Sergio Garcia and Rafael Cabrera-Bello were three up after seven against JB Holmes and Ryan Moore - one of two new American pairings for the day's second session.
The other fresh American duo - Brandt Snedeker and Brooks Koepka - held a commanding advantage over Danny Willett and Martin Kaymer at three up through six.
There was more good news for Europe in the final match, though, with Rory McIlroy and Thomas Pieters three up after six against Dustin Johnson and Matt Kuchar, who had thrashed the Belgian and Lee Westwood earlier in the day.
