For Weir, Choi and Ogilvy, the Sept 22 to Sept 25 Presidents Cup in North Carolina will mark their third stint as assistants while Villegas will make his first appearance as an assistant.

Canada’s Weir served as assistant to Nick Price in 2017 and Ernie Els in 2019 and competed in five Presidents Cups where the former Masters champion went 13-9-2.

Eight-time PGA Tour winner Choi, who first served as a captain’s assistant when the Presidents Cup made its debut in his homeland of South Korea in 2015, has competed in the event three times and owns a 6-8 overall record.

Former US Open champion Ogilvy was first selected as an assistant in 2017 after the Australian had appeared on three International teams and amassed a 7-6-1 record.

Villegas has made one Presidents Cup appearance, having competed in the 2009 event at TPC Harding Park in San Francisco, and the four-time PGA Tour winner is the only Colombian player to compete in the biennial showdown.

“Bringing in Camilo as my fourth assistant captain feels like the absolute perfect way to round out my selections,” Immelman said in a news release.

“For the International team, developing a well-rounded team is imperative. When I look at the representation among countries, languages and cultures, my ultimate goal is to blend them as cohesively as possible, and Camilo will help us do just that.”

The Presidents Cup pits a 12-man team from the US against international players from outside Europe.

The US have dominated the competition winning on 11 of the 13 occasions it has been held, including each of the last eight.
