WHAT HAPPENED: Despite dominating the WTA tour by winning six doubles titles since pairing up in March, Martina Hingis and Chan Yung-jan hadn't tasted Grand Slam glory.

Until now.

The No. 2 seeds rolled past No.7 seeds Katerina Siniakova and Lucie Hradecka to win the women's doubles crown at the US Open on Sunday, 6-3, 6-2. The title is the 13th Grand Slam women's doubles title for Hingis, and third at the US Open, while it is the first doubles major for Chan after three runner-up showings. 

"[To win] my first title, it's amazing -- especially I have Martina on my side. I have been to the final several times, and it's the first time really to win a Grand Slam," Chan said. "It's very, very special for me. Today was a great match. We started really strong and really aggressive." 

Hingis also went two-for-two in her appearances in the doubles finals at this tournament, as she claimed the mixed doubles crown with Jamie Murray on Saturday, defeating her partner's sister, Chan Hao-ching and Michael Venus of New Zealand in a match tiebreak.

Hardly trailing in the match insider Arthur Ashe Stadium, Chan and Hingis were on point throughout the 65-minute final, striking 22 winners to just two unforced errors in the match, and breaking serve three times. 

In the first Grand Slam final for the No. 7 seeded Czech team together -- Hradecka had won two previously with compatriot Andrea Hlavackova, including the 2013 US Open -- won just 11 points on return in the entire match, while striking 23 winners to 18 errors of their own.

WHAT IT MEANS: The No. 2 seeds saw their French Open and Wimbledon campaigns end before the final, losing in the semifinals and quarterfinals, respectively. However, the duo peaked at the right time in New York, winning the title without the loss of a set.

"I think we had definitely our chances [before]. Semifinals at the French, we played really well, but they were just better on that given day, Lucie [Safarova] and Bethanie [Mattek-Sands]," Hingis said. "Coming into this tournament, winning Cincinnati, we showed that we can play on clay, and we can play on grass, and I think already making the finals, we felt very comfortable with how we played in the previous two, three matches.

"I think we played, already had a good warmup, and everything kind of fell into place. I think it was more, for me especially, was a disappointing Wimbledon. I think we could've, should've done better. We were pumped up to go all the way here."

For Chan, who reached the final in doubles in her debut as an 18-year-old in 2007 alongside compatriot Chuang Chia-jung, her first Grand Slam title is the culmination of a long road to the top. The duo has now won seven titles on the season on all three surfaces.

"It's been a very amazing journey to make it all the way here, and since the first day we agreed to play together, next day I said, 'Oh, Martina said yes to me.' That means I'm going to play beside my own idol, and we are going to fight together. That's a huge step for my whole career. To win this title together, it's really amazing."

MATCH POINT: With the victory in the US Open final, Hingis will rise to No. 2 in the WTA doubles rankings with Chan sitting right behind her at No. 3. Both players are chasing Czech Lucie Safarova in the top spot, but Hingis will sit 550 points behind Safarova on Monday.

Can she return to the top spot before season's end?
