Golf uses a par scoring system. Par is set for each hole and the entire 18-hole course. Scoring is based on the number of strokes taken compared to par. Most tournaments are played over four rounds, with the lowest score in relation to par winning.
Tiger Woods shot 70, 68, 67 and 70 to win the 2019 Masters at the Par 72 Augusta course. That means he shot -13 to win his fifth green jacket.
