Europe took an important step Friday toward winning the Solheim Cup on American soil.

Carlota Ciganda salvaged an unlikely par from a hazard on the par-5 15th hole after an incorrect ruling. Suzann Pettersen then won the next hole with a birdie, sending them from 2 down at the turn to a 1-up win in a pivotal fourballs (best-ball) match that staked Europe to a 5-3 lead.

A day at Colorado Golf Club in Parker ended with Stacy Lewis, on the losing end of that match, getting into a heated discussion with an official over the use of a laser by the official to determine the right drop for Ciganda.

"Part of the problem was the rules official lasered the flag and made it public information. So he gave them a (yardage) number," Lewis said.

Turns out that wasn't the problem. Ciganda was allowed to drop 40 yards behind, which isn't permitted under Rule 26-1-c. She hit her fourth shot just off the green and holed a 15-foot putt.

It was a tough day for Lewis, coming off a Women's British Open title. She struggled with the pace of greens on the front nine as she and Lizette Salas fell too far behind to catch up in morning foursomes (alternate-shot). Lewis played with Lexi Thompson in the fourballs.

The day was not a total loss for Meg Mallon's U.S. squad. She was scrutinized for taking Michelle Wie as a captain's pick, but Wie and Cristie Kerr disposed of Catriona Matthew and Charley Hull 2 and 1 in the final match.

PGA Tour: Patrick Reed shot a 6-under 64 to take a one-stroke lead over John Huh (62) at the Wyndham Championship in Greensboro, N.C. Reed had an 11-under 129 total. Jordan Spieth (66) was 9 under, while former Cal star Charlie Wi (65) was in a large group at 7 under.

Champions Tour: Kenny Perry had a 7-under 65 to take a one-shot lead at the Dick's Sporting Goods Open at En-Joie Golf Club (N.Y.). Joel Edwards and brothers Bart and Brad Bryant shared second.
