Three-time Grand Slam champion Andy Murray climbed 457 places in the ATP world rankings on Monday, despite withdrawing from the Washington Open before his quarter-final last week.
The former world number one is now ranked 375 as he continues his comeback from an 11-month injury layoff.
Murray also pulled out of the Rogers Cup in Toronto, though, after winning his last-16 match in Washington DC at 3 a.m.
Alexander Zverev remained as the world number three by successfully defending his Washington title with a straight-sets win over Alex De Minaur, while fourth-ranked Juan Martin del Potro was beaten in the Los Cabos final by Fabio Fognini, who jumps a spot to 14th.
