The Republic of Ireland native earned his place in the field by capturing the 2019 Amateur Championship at Portmarnock, 2 up, over Euan Walker. It was only the second time in 134 playings that the world's oldest amateur competition was contested at Portmarnock, and Sugrue took advantage of being at "home." Sugrue later represented Great Britain and Ireland in the Walker Cup Match at Royal Liverpool in Hoylake, England. He also competed in the 2019 U.S. Amateur at Pinehurst, falling in the Round of 64 to Walker Cup teammate Alex Fitzpatrick, 5 and 4. His Amateur victory earned Sugrue an exemption into the Open Championship at Royal Portrush in Northern Ireland, where he shot rounds of 71-73, but missed the 36-hole cut.
