NEW YORK — Swiss second seed Roger Federer faces a danger match against big-hitting American John Isner in fourth-round action at the U.S. Open on Monday.
Five-times U.S. Open champion Federer will start a warm favorite, but will take nothing for granted when he takes to the Arthur Ashe Stadium court against the 13th seed for the final match of the night.
Federer has a 4-1 career record against Isner.
Also on Monday, third seed Andy Murray continues his quest for a second U.S. Open title when he meets Kevin Anderson.
South African Anderson, the 15th seed, has been in good form, winning a small lead-up tournament in North Carolina on his way to New York.
