Lexi Thompson and Christie Kerr earned a point for the United States to trail Europe 8-5 in the Solheim Cup before the other fourball matches were suspended Saturday due to bad light.
The American duo defeated Spanish pair Carlota Ciganda and Azahara Munoz 3 and 2 to reduce the Europeans' lead after a good morning for the home team.
The U.S. held a slight advantage in the three remaining fourball matches, which will be resumed Sunday morning at St. Leon-Rot Golf Club in Germany.
Earlier Saturday, Charley Hull and Suzann Pettersen recovered from 4 down to win 1 up against Paula Creamer and Morgan Pressel, as Europe took a commanding lead from the morning's foursome matches.
The event will end Sunday with 12 singles matches after the suspended fourball matches are played.
