PARIS (AP) — Carlos Alcaraz called himself for breaking the rules at the French Open and conceded a point to Ben Shelton on Sunday during the defending champion's 7-6 (8), 6-3, 4-6, 6-4 victory in the fourth round.

Early in the second set, Shelton whipped a passing shot well out of Alcaraz's reach up at the net. So Alcaraz flung his racket — and, as his equipment flipped through the air, its strings somehow not only made contact with the ball but sent it back over the net and onto the other side of the court.

Initially, the second-seeded Alcaraz was awarded the point. But he immediately went over to the chair umpire to admit that he wasn't holding his racket when it touched the ball. That's not allowed, so the point went to Shelton, an American seeded 13th.

When the official informed the Court Philippe-Chatrier crowd what had happened, Alcaraz was given a round of applause.

This all happened at what could have been a critical moment, because instead of leading 40-30 on his serve, Alcaraz was now down 30-40, giving Shelton his first break point of the match. But Alcaraz saved that one — and five others in that 20-point game — along the way to taking a two-set lead in an entertaining matchup between a pair of 22-year-olds who hit the ball hard.

The 13th-seeded Shelton, twice a semifinalist at majors, delivered serves at up to 143 mph (230 kph) and forehands at up to 116 mph (187 kph). Alcaraz, already a four-time Grand Slam champion, showed off various parts of his repertoire.

It was tighter than the score might indicate: Shelton held three opportunities to own the opening set, leading in the tiebreaker at 6-4, 6-5 and 7-6. Take any of the subsequent points, and Shelton would own that set.

But Alcaraz — who meets No. 12 Tommy Paul of the U.S. in the quarterfinals Tuesday — saved the first with a service winner. Shelton netted a backhand on the next. And the last ended with Shelton smacking a backhand right at the body of Alcaraz, who was up at the net and contorted himself in order to chop a drop volley winner.

Alcaraz then converted his second set point, closing a 15-stroke exchange with a down-the-line forehand that drew a mistake from Shelton.

The third set went to Shelton when Alcaraz put a forehand into the net, and the big-swinging American punched the air, then his chest, and screamed: “Let's go, baby! Come on!”

The fourth swung Alcaraz’s way when he used a drop shot winner to set up a break point that he claimed for a 2-1 edge and, after a total of 3 hours, 19 minutes, he was able to finish off an 11th consecutive win at Roland-Garros.
