At the end of a long and eventful day at Wimbledon Friday, the U.S. men had one and a half men still contending in the singles draw. Not that bad, considering only seven had made it in the first place.
Leading the way, so far, was unheralded wild-card entry Denis Kudla, who made his way into the round of 16 of a major for the first time.
The Fairfax, Va., player beat Santiago Giraldo of Colombia, 6-2, 6-7 (3), 2-6, 6-1, 6-3.
Kudla left the Wimbledon grounds not knowing who his next opponent would be. So did everybody else.
Cilic, last year's U.S. Open champion, seeded ninth here, and a big server at 6 feet 6, and Isner, seeded 17th and 6-10, played for 4 hours 16 minutes and were tied at 10-10 in the fifth set when daylight ran out.
Wimbledon plays no fifth-set tiebreakers, so the players will carry on Saturday. Isner was involved in the longest match played here, or anywhere, with an 11-hour 5-minute victory, over three days, against Nicholas Mahut in 2010. Isner won that fifth set, 70-68.
Isner-Cilic was a typical Wimbledon big-server match, one of those that always seems to be in search of a break point. There were few in this one, with three of the first four sets going to a tiebreaker and Cilic winning the other set, the third, 6-4.
Cruising along, and probably oblivious to all this, was top-seeded Novak Djokovic, who beat Bernard Tomic of Australia, 6-3, 6-3, 6-3.
The U.S. women's prospects had a mixed day.
San Diego's CoCo Vandeweghe pulled a stunner on former U.S. Open champion Samantha Stosur. Vandeweghe, of the well-known basketball Vandeweghe family, won, 6-2, 6-0.
The Bryan brothers, Bob and Mike of Camarillo, the top-seeded men's doubles team, got past two other U.S. players, defeating Steve Johnson and Sam Querrey, 6-1, 5-7, 7-6 (3), 6-3.
Last year, Kyrgios eliminated Rafael Nadal in the fourth round.
