LONDON (AP) — Top-ranked Andy Murray headed a list of high-profile departures in the first round at Queen’s on Tuesday, with the Wimbledon champion losing to a player who found out he was competing only on the morning of the match.

Murray put in a sloppy and error-prone display in losing to 90th-ranked Jordan Thompson 7-6 (4), 6-2, joining Stan Wawrinka and Milos Raonic in getting eliminated on a day of shocks at the Wimbledon warmup event. They were the top three seeds.

Thompson, who lost in the final round of qualifying on Sunday, stepped up to play Murray following the withdrawal early Tuesday of Aljaz Bedene because of a wrist injury. Thompson played the match of his life — but was given a helping hand by the erratic Murray, the defending and five-time champion in west London.

The Australian sealed victory with an ace down the middle.

“Definitely the biggest win of my career,” Thompson said.

“Yesterday, I was sitting around, hoping to be able to get a game,” he added, “but there weren’t too many matches yesterday. I was always coming in, trying to sign in, and here I am in the draw. I’m so lucky.”

It was Murray’s first loss at Queen’s since 2014, ended his 14-match winning run on grass dating to 2015, and is a setback to his preparation for Wimbledon, which starts on July 3.

“It’s a big blow, for sure,” said Murray, whose forehand was particularly errant and had a first-serve percentage of just 55. “It has happened in the past where guys haven’t done well here and gone on to do well at Wimbledon.

“There is no guarantee that I won’t do well at Wimbledon, but it certainly would have helped to have had more matches.”

Both of Murray’s titles at Wimbledon, in 2013 and ’16, came after winning Queen’s.
