LONDON -- It was the biggest day of the tennis season, as every remaining player in the draw (16 men, 16 women) was in action at Wimbledon. Miss anything? Our writers around the ground recap every match:
Women's draw
Garbine Muguruza def. Angelique Kerber 4-6, 6-4, 6-4
Key stat: Muguruza made 38 more unforced errors (50-12) than Kerber, yet both women won the same number of points (101) in the match. How? Muguruza hit 55 winners to Kerber's 27.
Key moment: By breaking Kerber in the final game and thus winning the match, Muguruza ended a streak: She had lost all four previous matches at Wimbledon in which she had lost the opening set.
No. 2 Simona Halep def. Victoria Azarenka 7-6 (3), 6-2
Key stat: Azarenka was her own worst enemy Monday, giving up 32 points on unforced errors to 11 for Halep. With Azarenka's loss, and a loss by world No. 1 Angelique Kerber earlier in the day, only four previous Slam winners remain in play. With one more win and a spot in the semifinals, Halep will take over the No. 1 spot from Kerber.
Key moment: Facing a first-set loss, Azarenka made five unforced errors, four of them on her forehand, to lose the tiebreak 7-3. She would drop the next five games, making 12 unforced errors and winning only 15 points in the first six games.
Venus Williams def. Ana Konjuh 6-3, 6-2
Key stat: Williams dominated with a strong and accurate serve. She converted 86 percent of her first serves in this match, and struck seven aces. Again and again, she drew free points either with outright winners on serve, or by forcing easy mistakes from her opponent. That kind of ball-striking appeared to add confidence to her entire game.
Key moment: This match was relatively even until early in the second set, when Konjuh's wheels came off. Just when the young Croatian, 19, needed to up her game, she began losing the range with her powerful groundstrokes. She missed long, in the net, and wide. When Konjuh didn't lose easy points with unforced errors, Williams was hitting winners or drawing unreturnable balls with her own strong ground strokes. Konjuh went down 5-1 in a flash, and the uphill climb was simply impossible to overcome.
Coco Vandeweghe def. Caroline Wozniacki 7-6 (4), 6-4
Key stat: Vandeweghe won 11 of 14 serve-and-volley points and played a total of 32 at the net, winning 22. New coach Pat Cash might be making a good grass-court player even better.
Key moment: Vandeweghe hit a deep backhand on Wozniacki's serve with the first-set tiebreaker poised at 4-4 to set up a crucial winning shot. The American rushed the net, won the point and went on to take the opening set. That gave her the lead that she never relinquished.
No. 6 Johanna Konta def. No. 21 Caroline Garcia 7-6 (3), 4-6, 6-4
Key stat: Konta played pristine ball down the stretch. In the final set, she cracked 11 winners and committed only two errors. Just another example of how tough she has been to beat in pressure matches this season.
Key moment: After Garcia pulled ahead 30-15 in what would be the final game, Konta landed a perfectly placed backhand winner down the line. Garcia then hit two balls into the net to end the contest. Konta is now the first British woman in the quarterfinals since Jo Durie in 1984 and is aiming to be the first to make it to the final since Virginia Wade won the title 40 years ago.
Magdalena Rybarikova def. Petra Martic 6-4, 2-6, 6-3
Key stat: Rarely seen on today's circuit, Rybarikova's game -- with her forward moving serve and delicately placed volleying -- lends itself to the serve-and-volley approach. She came to the net 27 times Monday, converting on 67 per cent.
Key moment: At a set all and 3-2 to Rybarikova in the third, Martic was serving to tie the match. A double fault from the Croatian gave Rybarikova a crucial 0-30 lead and resulted in a behavioral warning for Martic. The Slovakian capitalized on the opportunity by taking the game. From there, the third set never looked in doubt.
Svetlana Kuznetsova def. Agnieszka Radwanska 6-2, 6-4
Key stat: Kuznetsova hit an impressive 37 winners, 10 more than she has produced in any of her previous matches in this tournament. Her confidence to go for such shots might explain why she's yet to drop a set.
Key moment: Radwanska hit a straightforward-looking baseline cross-court forehand wide on break point at 3-3 in the second set. She had fought hard to get back into contention after a poor first set but paid for the error as Kuznetsova consolidated next game and closed out the match.
No. 13 Jelena Ostapenko def. No. 4 Elina Svitolina 6-3, 7-6 (6)
Key stat: Svitolina simply could not find her first serve in the first set, hitting only 45 percent. That allowed the ever-aggressive Ostapenko to feast on the second serve, winning 76 percent of those points, and breaking her opponent three times in the first set alone. Against a confident player in Ostapenko -- with the success of Roland Garros still in her sails -- it was too much to concede.
Key moment: Ostapenko had been in complete control until squandering two match points at 5-4 in the second set. Needing to break Svitolina to force a tiebreaker, the Latvian did just that. Her nickname "Alona" means strong as oak. It could easily mean heart of a lion, too.
Men's draw
No. 1 Andy Murray def. Benoit Paire 7-6 (1), 6-4, 6-4
Key stat: An extremely ugly 44 unforced errors, to go along with 10 double faults for Paire, who played a typically erratic match (he also had 50 winners). By contrast, reigning champion Murray made just eight unforced errors, did not have a single double fault and struck 25 clean winners.
Key moment: The first-set tiebreaker. If Paire wins it, perhaps he has a solid chance to come away as the victor in this match, particularly since the top-seeded Murray is battling a balky hip and looked less than comfortable at times on Monday. But Paire is one of the tour's more unpredictable performers, and he played meekly when it counted most. Multiple easy errors in the tiebreaker, plus sour body language, and not all that much fight. Meantime, Murray played smart, contained tennis, doing just enough, making sure not to give away anything without a scramble. The last two sets played essentially to the same script.
No. 3 Roger Federer def. No. 13 Grigor Dimitrov 6-4, 6-2, 6-4
Key stat: Big upset wins at Grand Slams are often triggered when the lesser player takes the first set, gains momentum and puts the favorite on his or her heels. Federer wasn't having any of that on Centre Court on Monday. From a statistical standpoint, his first set was extremely clean: eight winners, just two unforced errors and three aces. He also won 84 percent of his first-serve points in that set. Those numbers simply smothered any Dimitrov upset hopes.
Key moment: After Federer broke to go up 5-4 in the first set, his service game was a master class in laying down the hammer. First, a stab volley winner. Then an aggressive forehand approach that drew an error. Then a serve out wide that forced a miss. And lastly, an ace. There was simply no doubt, no letting up, no loose ends. Dimitrov, who grew up styling his every stroke after Federer's, got the signal that the man he'd grown up idolizing meant business on Monday. Serious business. They played two more sets, but the match was essentially finished after Federer cruised through that service game to take the first set.
No. 16 Gilles Muller def. No. 4 Rafael Nadal 6-3, 6-4, 3-6, 4-6, 15-13
Key stat: Four hours, 48 minutes of tension-convention tennis. The longest match of the tournament. Nadal also cracked a career-high 23 aces, but it wasn't enough. Muller, 34, finally won on his fifth match point.
Key moment: So many, but in the end Nadal would lose the final game after back-to-back forehand errors. It was the deepest five-set match of Nadal's career, but in the end, he will have to wait until the US Open to try to win multiple majors this season.
After nearly 5 hours and 28 games in the fifth set ...

No. 6 Milos Raonic def. No. 10 Alexander Zverev 4-6, 7-5, 4-6, 7-5, 6-1
Key stat: Zverev returned wonderfully at times and created 17 break points against a serve that frequently topped 130 mph. He capitalized on just three of them, though, while Raonic converted five out of eight against an equally blistering bombardment. The Canadian will need similar guts against Roger Federer in the quarterfinals.
Key moment: There had been just one point dropped on serve in the fifth set when Raonic broke Zverev in the fourth game. The forehand passing shot down the line was a thing of beauty. It was the first time Raonic took the lead in the match, and he never looked back.
No. 24 Sam Querrey def. Kevin Anderson 5-7, 7-6 (5), 6-3, 6-7 (11), 6-3
Key stat: The 6-foot-6 Querrey and 6-8 Anderson -- with their similar big-serving playing styles -- were incredibly evenly matched. Both players hit 31 aces. Querrey, though, converted 59 percent of his second-serve points (to Anderson's 50 percent) and that made the difference.
Key moment: After letting four match points slip away in the fourth-set tiebreaker, it was crucial that Querrey convert on every next opportunity. Anderson started to look tired in the fifth set; his ball toss was lower and his feet moved slower. Querrey capitalized in the sixth game. Stepping up the power and running Anderson deep into the corners, Querrey broke at love to take a crucial 4-2 lead that he never relinquished.
No. 7 Marin Cilic def. No. 18 Roberto Bautista Agut 6-2, 6-2, 6-2
Key stat: Cilic averaged 21 aces per match in the first week. That number dropped against Bautista Agut to nine, partly because Cilic won in straight sets. But it only accentuated his movement and touch. Cilic won 83 percent of net points. Should he keep that up, the No. 7 seed could make it past the Wimbledon quarterfinal stage for the first time.
Key moment: Bautista Agut had failed to capitalize on four opportunities to break the Cilic serve before finally doing so midway through the second set. The effort, though, did not help Bautista Agut, who was immediately broken back, ending any chance to grab a lead in the match.
No. 11 Tomas Berdych def. Dominic Thiem 6-3, 6-7 (1), 6-3, 3-6, 6-3
Key stat: Berdych's first serve went in 74 percent of the time (101 of 141), compared to Thiem's 56 percent. The Czech won 83 percent of his first-serve points, too, and more than half -- 55 percent -- weren't returned.
Key moment: Strong forehand and baseline hitting from Berdych in the second game of the final set eventually forced an error from Thiem in a six-shot rally and gave the Czech a break from which he never looked back.
