Murray, who has previously won Wimbledon twice, is currently recovering from surgery on a long-standing hip injury with his inactivity causing his slide to world No.21, a position he has not held since Aug. 2006.

The two-time Olympic champion broke into the top 100 back in Sept. 2005 and held the world No. 1 spot between Nov. 2016 and Aug. 2017.

He now finds himself just one place below Spain's Albert Ramos-Vinolas in the latest ATP rankings, and seven behind No. 14 Novak Djokovic.

Murray hasn't played competitive tennis since last year's Wimbledon, where he was eliminated by Sam Querrey.
