The Australians forced the playoff by shooting a 2-under 70 in alternate-shot play at the PGA Tour’s lone regular-season team event for a four-round 268. Oosthuizen and Schwartzel began the round with a one-stroke lead but shot a 71 with three pars and two bogeys.
In the playoff, Smith and Leishman ended it with a par on their second trip up the par-5 18th, after Oosthuizen pushed his tee shot into the water and narrowly missed an 11-foot putt for par.
It was Smith’s best result since tying for second at the pandemic-delayed 2020 Masters in November. It’s also was his sixth top 10 since the current tour season started.
It was Leishman’s sixth career victory, his best result since tying for fifth at the Masters this month and his first win since the 2020 Farmers Insurance Open.
The climactic finish capped off a compelling duel between two teams that teed off together in the final grouping and took turns holding leads that never grew to more than two strokes.
