Each day of Wimbledon, Baseline will sum up the action with a photo gallery of the top surprises.

Gauff Stuns Her Idol

Qualifier Cori "CoCo" Gauff drew her idol Venus Williams in the first round of her Wimbledon debut, and was thrilled. Undeterred by the grand occasion, the 15-year-old wild card stunned the seven-time Grand Slam champion, 6-4, 6-4.

"This was definitely the first time I ever cried after a match—after winning, obviously," Gauff said. "I don't even know how to explain how I feel... I wouldn't be here if it wasn't for her." 

At 39, Williams is 24 years older than Gauff, the biggest age gap in a WTA match since 2004.

Osaka Bows Out

Going into the first-round encounter, Yulia Putintseva had a 2-0 record over world No. 2 Naomi Osaka, yet it was still a shock to see the Australian and US Open champion knocked out so early. Putintseva did well to win the first-set tiebreak and run away with the match, 7-6 (4), 6-2. The 21-year-old struggled throughout the match and in press, leaving early because she felt tears coming on.

Auger-Aliassime's Milestone

It's not surprising that Felix Auger-Aliassime beat fellow Canadian Vasek Pospisil, who's playing his first tournament after back surgery. It is surprising that it's the 18-year-old's first-ever Grand Slam win. He's ranked No. 21, meaning he is seeded at the major, and has a 27-14 record in 2019.

Tsitsipas Tumbles

The No. 7 seed figuratively and literally tumbled out in the first round to Thomas Fabbiano in a 6-3 fifth set. Tstisipas has done nothing but rise during his young career, and was defending a fourth-round finish. Still, he's safely inside the Top 10 and has the hard-court season to look forward to, where he first started cranking out impressive results in 2017.

Brengle Bounces Vondrousova 

Fourteen Americans took the court on Monday, and the six that managed to win did so in dominating style. Madison Brengle may have scored the most impressive victory by taking out French Open finalist Marketa Vondrousova, 6-4, 6-4. Danielle Collins, Madison Keys, Sofia Kenin, Denis Kudla and Reilly Opelka all also won in straight sets.
