Just before darkness fell, so did Carlota Ciganda's eagle, leaving the United States at a deficit Friday after the first day of the Solheim Cup.

Europe led the United States 4-2 at St. Leon-Rot Golf Club in Germany in the biennial event.

Ciganda, of Spain, holed a 9-iron from 135 yards to win the 17th hole as she and Melissa Reid of England came from 2 down to draw level with Cristie Kerr and Lexi Thompson with one hole left before play was suspended because of bad light.

"They fought on the back nine to get a few holes going their way," Thompson said. "But we'll come back tomorrow early to finish our last hole. We're pumped. We're going to be ready."

German duo Sandra Gal and Caroline Masson were 1 up through 15 holes against Gerina Piller and Brittany Lang in the other uncompleted match.

Nineteen-year-old Charley Hull of England led the charge for Europe by winning both of her matches.

Europe is going for its third consecutive title in the competition; the U.S. last won in 2009.

Day leads PGA Tour event

•A long day for Jason Day ended even better than it began, thanks to an eagle putt at the 18th that extended his lead to five shots at the PGA Tour's BMW Championship in Lake Forest, Ill. He shot an 8-under 63 to set a 36-hole tournament record at 18 under. Day returned to the course early Friday to finish his rain-delayed first round. He needed to hole a 44-yard wedge shot for a 59 but made par instead, narrowly missing a birdie putt and carding a 61.

Tiger Woods revealed he underwent a second microdiscectomy surgery on his back. Woods made the announcement on his website and reported the microsurgical procedure — intended to relieve pain from a pinched nerve — was performed late Wednesday in Park City, Utah, by the same neurosurgeon who performed the initial operation in March 2014.

Players say coach ordered hit

A Texas high school football coach directed two players to strike a referee during a game because of missed calls that had hurt the team, the players claimed during a national broadcast.

During an appearance on ABC's "Good Morning, America," Michael Moreno and Victor Rojas also repeated earlier claims that the ref had used racial slurs.

Moreno said he regrets hitting the ref, Robert Watts, and wants to apologize. Rojas said he was just doing what he was told.

The players didn't name the accused coach; the school district has suspended assistant coach Mack Breed pending an investigation.

Harvick gets pole on practice lap

Kevin Harvick will begin defense of his Sprint Cup championship from the pole in the opening round of NASCAR's playoffs.

Rain washed out qualifying Friday at Chicagoland Speedway, and NASCAR set the field based on speeds from practice. Knowing that weather was likely going to be an issue, Harvick and his Stewart-Haas Racing team focused on laying down a fast lap in practice.

Rain also caused the Truck Series race to be rescheduled for Saturday.
