Dan Evans pushed through a tough two-setter against South African Kevin Anderson to book an all-British second round match with Cameron Norrie at the San Diego Open on Tuesday.
The eighth seed overcame the 35-year-old former Wimbledon finalist - a lucky loser from qualifying - after a marathon first set tiebreak, winning 7-6 (11) 7-5 in two hours and 18 minutes.
Anderson, who made the Wimbledon final in 2018 and the US Open final in 2017, gave his 31-year-old opponent a torrid time on serve, pounding down 13 aces to Evans's five.
Both had a handful of chances to wrap up the first set in the tiebreaker.
