PARIS, France - Barbora Krejcikova and Katerina Siniakova wrapped up a weekend of first-time Grand Slam champions on the WTA on Sunday, as the Czech pair defeated Japan's Eri Hozumi and Makoto Ninomiya to win the French Open, 6-3, 6-3.

After Simona Halep won her first singles major title, and Latisha Chan secured her first mixed doubles major, the 22-year-old Czechs joined the Grand Slam club - in women's doubles, at least - in one hour and five minutes on Court Philippe Chatrier. 

In juniors, the Czechs had quite the extensive doubles pedigree, winning the French Open five years ago en route to three total girls' doubles trophies in 2013, and also won the junior Wimbledon and junior US Open doubles titles that year.

Krejcikova and Siniakova became the first all-Czech pairing to win the women's title in Paris since Andrea Hlavackova and Lucie Hradecka in 2011 in the fifth Grand Slam they contested together.

Conversely, the unseeded Hozumi and Ninomiya were the first all-Japanese duo to reach a Grand Slam final in women's doubles.

They knocked out the top-seeded Australian Open champions Timea Babos and Kristina Mladenovic in the quarterfinals, ending the Hungarian's chances of ascending to the World No.1 ranking at the close of the fortnight.

Though the Japanese pair had not lost a set in five previous matches, they were unable to hold off the Czech pair on serve for much of the match.

Krejcikova and Siniakova were a perfect 4-for-4 on break point conversions, and won nearly half of the points played on return in the match, while only dropping serve once themselves.

They are the sixth and seventh Roland Garros doubles champions from the Czech Republic, giving the country sole possession of fourth place for most doubles champions in the Open Era at the tournament – behind Spain (9), France (10) and the United States (33).
