Golf originated in Scotland and England, who have debated its invention. Major golf tournaments include the Masters in April, US Open in June, British Open in July, and PGA Championship in August. A golfer's career success is often defined by how many major tournaments they win. Golf requires basic equipment like clubs, balls, tees, bags, and shoes. The objective is to complete holes in the fewest shots by following rules of etiquette and fair play. Golf is played worldwide but originated in and remains popular in Scotland, Britain, the US, and Asia. Popular golf athletes are Tiger Woods, one of the best ever who won early in his career, and his longtime rival Phil Mickelson.
