Cameron Davis and Harrison Endycott each shot 5-under 66 on Thursday at Iberostar Playa Paraiso to help Australia take an eight-stroke lead in the World Amateur Team Championship.
A stroke behind Scotland after the opening round at Iberostar Playa Paraiso, Australia had a 19-under 267 total — one off the 36-hole record set by the United States in 2012. The best two scores count in the total for the three-man teams, with U.S. Amateur champion Curtis Luck again lagged behind his teammates with a 71.
Davis topped the individual standings at 10-under 133, a stroke ahead of Endycott and two in front of Poland's Adrian Meronk (69).
Australia matched the best second-round total in event history at 10-under 132. It won the Eisenhower Trophy in 1958, 1966 and 1996.
The two-time defending champion United States was second. Stanford's Maverick McNealy and Texas' Scottie Scheffler shot 69 at Mayakoba El Camaleon, and Oklahoma's Brad Dalke had a non-counting 72.
Switzerland was third at 10 under. Jeremy Freiburghaus shot 68, and Mathias Eggenberger 71 at Iberostar Playa Paraiso. Poland was fourth at 9 under, and Scotland fifth at 8 under.
