Lammons & Withrow claim Washington crown

Americans Nathaniel Lammons and Jackson Withrow have jumped into Nitto ATP Finals qualifying contention after claiming their second title in as many weeks in the final of the Mubadala Citi DC Open Sunday.

After winning in Atlanta last week, the pair defeated Brazilian duo Marcelo Melo and Rafael Matos 7-5, 6-3 in the final in Washington. They became the first all-American champions at the ATP 500 since Bob Bryan and Mike Bryan in 2015.

"Lucky for us it was a little hot and we could kind of bring the heat today," Lammons said during the trophy ceremony. "Thanks to my partner Jackson. We got some good momentum going the last couple of weeks. We love playing here in the States."

The Americans put on a strong display of serving, winning 87 per cent of their first-serve points, according to Infosys ATP Stats. They dropped just 10 points on serve and defended both break points against them en route to taking an eighth ATP Tour title as a pair.

After the home triumph, Withrow thanked the Washington fans for their support: "You guys have been amazing all week for us," he told the stadium crowd. "We feel the energy, we feel like you guys love doubles."

Rising four places to ninth in the PIF ATP Doubles Rankings, the Americans head to the National Bank Open Presented by Rogers in Montreal, where they will face Tomas Martin Etcheverry and Alejandro Tabilo in the opening round.
