WIMBLEDON, England — For the second straight year, the American Sam Querrey wound up smiling after a prodigious Friday-Saturday third round at Wimbledon.

Where in 2016, he finished a suspended match on Saturday to upend No. 1 Novak Djokovic in four sets in a genuine stunner, on Saturday he played just one game and finished an impressive third-round win over the No. 10-ranked Frenchman, Jo-Wilfried Tsonga.

The No. 29-ranked Querrey’s 6-2, 3-6, 7-6 (7-5), 1-6, 7-5 win gave him his second Wimbledon fourth round where, if he can surpass the No. 42-ranked Kevin Anderson of South Africa, he can find his second Wimbledon quarterfinal and his second Grand Slam quarterfinal.

“I can’t wait,” he told the BBC immediately afterward, referring to Monday’s fourth round.

As Querrey, 29, explained to the BBC, he offered Friday night to play one more game on Tsonga’s serve as darkness set in after 9 p.m., with Querrey leading 6-5 in the fifth set. Tsonga opted to wait and continue playing on Saturday.

On Saturday, Tsonga served to a 40-30 lead, before Querrey drove a marvelous backhand winner up the line to get to deuce. From there, Tsonga erred. First, he charged forth per custom for a backhand volley, which he netted to give Querrey a match point. And on that match point, he yanked his first groundstroke, a forehand, wide into the doubles lane.

Querrey smiled and gently pumped his right fist, while Tsonga, a second-week mainstay who has reached a Grand Slam final, five semifinals and nine quarterfinals, extracted a ball from his pocket and blasted it away in disgust. “Frustrated, of course, because it was short,” Tsonga said.

He did not blame the circumstances, saying the light had been too difficult to continue on Friday night and said, “I’m frustrated because I lost in two minutes.”

Said Querrey to the BBC, “I think it’s always tough to come out and serve first like he had to.” He called the outcome “anticlimactic” after their two hours 58 minutes of tennis, spread across a Friday evening and a Saturday midday.
