Two-time Wimbledon champion Andy Murray reiterated Monday that he is likely to retire from tennis before the season is over. “I’m likely not going to play past this summer," the 36-year-old Murray said after losing 6-2, 6-4 to fifth-seeded Ugo Humbert at the Dubai Championships. After rallying past Denis Shapovalov in three sets on Monday for his 500th hard-court win, the 36-year-old Murray hinted he was heading into the “last few months” of his career.
