Murray will next play Italian Matteo Viola, ranked 240th in the world. The two-time Wimbledon champion is using the tournament to work his way back toward his best after having hip surgery in January. He returned to the courts in June playing doubles — including at Wimbledon — before moving back to singles this month.
The British player had lost to Richard Gasquet in Cincinnati and to Tennys Sandgren in Winston-Salem, both in the first round. Murray had not played on the Challenger Tour since 2005.
