Andy Murray equalled Lleyton Hewitt by claiming his 47th main-draw win at the US Open as he came through a tricky first-round clash with Francisco Cerundolo.
Just under 10 years on from his maiden grand slam triumph at Flushing Meadows, where he famously beat Novak Djokovic in a near five-hour final, Murray overcame 24th seed Cerundolo in relatively short order.
The world number 51 produced one of the more impressive performances since his return from hip surgery to win 7-5 6-3 6-3 in two hours and 42 minutes on the Louis Armstrong Stadium court.
It is a success that moved him level with Australian great Hewitt, with whom he now shares ninth place on the all-time list for the most main-draw wins in New York.
Additionally, it marked Murray's first straight-sets win at a grand slam since his fourth-round victory over Benoit Paire at Wimbledon in 2017.
Cerundolo, meanwhile, is still awaiting his first main-draw win at a major.
He has enjoyed a breakthrough year, winning his first ATP title at the Swedish Open in July and reaching a career-high ranking of 24, but fell at the first hurdle for the third successive major having failed to qualify for the Australian Open at the start of the year.
Murray will play John Millman or Emilio Nava in the second round.
