10 Things to Know, Day 9: Djokovic going for 25th straight win at Slam

Trivia: Which player playing today has parents who were Moldovan Olympians? Check back tomorrow for the answer.

It’s Rafael Nadal’s 33rd birthday today

The world No. 2 is one of six 30-somethings in the ATP’s Top 10 right now, along with Roger Federer (37), John Isner (34), Keving Anderson (33), Novak Djokovic (32) and Juan Martin del Potro (30).

The last spots in the quarterfinals are up for grabs

The top half of both draws play their fourth round matches, with the men’s No. 1, Djokovic, trying to reach a winning streak milestone.

Djokovic is going for his 25th straight win at a major

The Serb comes into his fourth round match against Jan-Lennard Struff on a 24-match winning streak at majors, going 7-0 to win 2018 Wimbledon, 7-0 to win the 2018 US Open, 7-0 to win the 2019 Australian Open and 3-0 so far at the 2019 French Open.

Djokovic is trying to reach his 13th career French Open quarterfinal

He would tie the record for most French Open quarterfinals for a man in tennis history—Nadal got to his 13th on Sunday.

Madison Keys has made the quarterfinals or better at four of the last six Slams

She’ll try to make that five of the last seven as she takes on Katerina **Siniakova, conqueror of women’s No. 1 Naomi Osaka in the last round.

Amanda Anisimova and Iga Swiatek are both going for a generational first

If either of them wins today, they’ll become the first player born in the 2000s, male or female, to reach the quarterfinals of a major.

AlionaBolsova will triple her career prize money here—at least

The Spaniard came into Roland Garros with $129,787 in career prize money. She gets approximately $270,000 for reaching the fourth round.

Dominic Thiem and Gael Monfils have been scheduled to play each other seven times before—but only played each other four times

Monfils gave Thiem walkovers at Cincinnati in 2016 (back injury) and Indian Wells this year (achilles), while Thiem gave Monfils a walkover at Doha in 2018 (viral illness).

Of the four times they did take the court, Thiem got four wins—the last two easily in straight sets.

The odds are even more stacked against Monfils: he is 0-11 against Top 4 players at majors.

His best win at a Grand Slam came against No. 5 David Ferrer in the 2008 French Open quarterfinals. Thiem is No. 4.

Fabio Fognini is also going for his biggest win at a major

The Italian, who plays No. 5 Alexander Zverev, is 0-7 against Top 5 players at majors. He did get two wins over Top 5 players in the lead-up season though, beating No. 2 Nadal and then-No. 3 Zverev (both in straight sets) en route to the Monte Carlo title.

Trivia Answer from yesterday: The only Argentine ever to beat Nadal at a major is Del Potro (twice), and the only two Argentines to beat Federer at a major are David Nalbandian (twice) and Del Potro (twice).
