International team captain Ernie Els has named Mike Weir, K.J. Choi and Trevor Immelman as assistant captains for this year's Presidents Cup. The trio will join the previously announced Geoff Ogilvy in the International team room in Australia this December.
Els served as an assistant in 2017 under Nick Price, and he emphasized a desire to create a "new formula" to help the International team win back the cup for the first time since 1998.
"In this instance I really wanted to try and start a new thinking process around the pairing system and so forth," Els said.
