WASHINGTON — Showing signs of returning to his old form, right down to the return winner on the last point, Andy Murray moved into the third round at the Citi Open by beating No. 4 seed Kyle Edmund 7-6 (4), 1-6, 6-4 on Wednesday for just his third victory since having hip surgery.

Murray is a three-time major champion and former No. 1 who was sidelined for 11 months because of his right hip. He missed the second half of 2017, had an operation in January, then returned to the tour briefly in June. One of his three matches that month was a loss on a grass court to Edmund, the Australian Open semifinalist who has supplanted Murray as Britain’s highest-ranked man.

There is still work to be done by Murray, of course. He is ranked 832nd, has played only five matches in the past 12 months, and needed three sets for each of his victories in Washington’s hard-court tuneup for the U.S. Open.

After a wayward second set against Edmund, Murray collected himself in the third, all the while barking at himself after miscues, as he is wont to do. He got the measure of Edmund’s serves late, earning two break points at 4-3. Another arrived at 5-4, thanks to a defensive lob that drew a long overhead from Edmund, followed by a double-fault. That brought match point, and Murray pounded a cross-court winner of an 83 mph second serve, then let out a loud yell.
