Tsitsipas, Isner, Murrays Feature In Washington; All You Need To Know
Tsitsipas, 21, reached the semi-finals on his tournament debut last year (l. to Zverev). Isner is a three-time finalist in Washington, and made his tour-level breakthrough here in 2007, when he posted a record five straight wins in a third-set tie-break before losing to Andy Roddick in the final.
The 48-player field also features two other Top 10 players, 23-year-old Russians Karen Khachanov and Daniil Medvedev, in addition to South African Kevin Anderson and Canadians Milos Raonic and Denis Shapovalov.
In doubles, Americans Bob Bryan and Mike Bryan return with their sights set on a record fifth title. Defending champion Jamie Murray will play alongside brother Andy Murray for the first time in nearly three years, while Tsitsipas will join forces with Nick Kyrgios.
