WIMBLEDON, England — The two-time champion Andy Murray withdrew from Wimbledon on Sunday, the eve of this year’s tournament, citing a persistent hip injury.

“I’ve made significant progress in practice and matches over the last 10 days, but after lengthy discussions with my team, we’ve decided that playing best-of-five-set matches might be a bit too soon in the recovery process,” Murray said in a statement on his Facebook page. “We did everything we could to try to be ready in time.”

The daunting nature of best-of-five matches, which the men play at Grand Slam events, probably has been a factor in the greater number of withdrawals from the men’s side of recent major tournaments. (Also a factor: a new rule that allows injured players to earn 50 percent of the first-round prize money at Grand Slam tournaments if they withdraw before their first match.)

Murray was the seventh man to withdraw from Wimbledon in the past week; only one woman has withdrawn. In May, eight men withdrew from the French Open before the first round, compared with two women.
