Grigor Dimitrov defeated Andy Murray 6-3, 6-4, 6-1 at the US Open on hard court in the first round, confirming his status as pre-match favourite with odds of 1.73 to Murray's 2.24. The Bulgarian dominated throughout, breaking serve consistently and limiting Murray's opportunities to build momentum in what proved a one-sided encounter. Murray, competing at the year's final Grand Slam, struggled to impose his game and failed to mount a sustained challenge in any of the three sets. Dimitrov's comprehensive victory signals strong form heading into the latter stages of the season and maintains his competitive edge over the British veteran in their head-to-head record.
