Alexander and Mischa Zverev have won their first doubles title as a pair in Montpellier. The brothers outclassed second-seeded Fabrice Martin and Daniel Nestor in a three-set battle 6-4 6-7 (3) 10-7. It took an hour and 26 minutes for the match to be concluded.
In their first tournament together, Martin and Nestor fell just short of making it all the way at an ATP event. The Zverev brothers won 40/47 (85%) of their first serve points and did save 5/5 (100%) of the break point chances they faced in the final.
Viktor Troicki and Nenad Zimonjic have captured the Garanti Koza Sofia Open doubles title on Sunday. Troicki and Zimonjic handed a loss to Mikhail Elgin and Andrey Kuznetsov in the final. The unseeded Serbian duo needed an hour of play to hand a loss to the Russian team 6-4 6-4.
Troicki and Zimonjic won their first doubles together this week in Sofia. On the other side, Elgin and Kuznetsov played for the second time ever together - and fell short just a win away from making it all the way. The key in the match was Troicki and Zimonjic converting 3/3 (100%) of their break point chances.
In Quito, Ecuador, the doubles final failed to see the finish line as a pair was forced to retire the match. James Cerretani and Philipp Oswald went all the way for the first in 2017 after a retirement from Julio Peralta and Horacio Zeballos.
Cerretani and Oswald were up by a set and had a 2-1 lead in the second set against Peralta and Zeballos, when their opponents decided to quit the clash. Cerretani and Oswald, who formed a team during last year's season, have notched their first ATP title after winning three of those on the ATP Challenger level previously.
Peralta and Zeballos have yet to win a title this season. Full results: Montpellier: Alexander Zverev (GER) & Mischa Zverev (GER) d.  Fabrice Martin (FRA) &  Daniel Nestor (CAN) 6-4 6-7 (3) 10-7
