What happened at the 2015 Open Championship
The final round was played on a Monday, only the second Monday finish in Open history, after rain and wind delays.
Oosthuizen holed a birdie putt at the 72nd hole to join Johnson (who birdied the 18th for 66) and Leishman in the playoff.
Louis Oosthuizen's 12-foot birdie putt at the 18th to force sudden death caught the left edge and stayed out, giving Zach Johnson a one-shot aggregate win.
