France's Nicolas Mahut and Pierre-Hugues Herbert won their second Rotterdam title after beating qualifiers Henri Kontinen and Jan-Lennard Struff in this year's doubles final at the tournament. Mahut and Herbert, who made it all the way in Rotterdam two years ago, didn't defend their title last year but returned to the tournament this year and edged out Kontinen and Struff 7-5 (5) 4-6 10-7 to win it all again.
The Frenchmen blew an early first set break but then saved three consecutive set points in the 10th game before they realized their first set point in the tie-break to win a tight opener. Kontinen and Struff broke Herbert and Mahut in the opening game of the second set and never faced a break point to force a decider but they fell short of completing a comeback win as the Frenchmen realized their first championship point in the match tie-break.
Elsewhere, Dominic Inglot and Aisam-Ul-Haq Qureshi won it all at the New York Open, while Marcel Granollers and Horacio Zeballos made it all the way in Buenos Aires. The fans in New York were hoping to see a local duo win it all but that didn't happen as Inglot and Qureshi edged out USA's Steve Johnson and Reilly Opelka 7-6 (5) 7-6 (6) to win their maiden team title.
Johnson and Opelka recovered from a break down in the first set and even saved three consecutive set points in the tie-break but still couldn't steal the opener as Inglot and Qureshi realized their fourth set to point to win a tight opener.
Johnson and Opelka then twice recovered from a break down in the second set but Inglot and Qureshi once again kept their focus as they got the job done in the tie-break to seal the title. Meanwhile in Buenos Aires, Granollers and Zeballos ultimately didn't pay the price for blowing so many chances as the top seeds were up by a set and had a break in the second set but even that wasn't enough for them to claim a straight-set win over Guillermo Duran and Juan Ignacio Londero.
Granollers and Zeballos further complicated things in the match tie-break but it all ended up well for them as they saved three match points in the third set before converting their sixth match point to seal a 6-4 5-7 18-16 win in an hour and 46 minutes of play.
