Collin Morikawa is an American professional golfer who plays on the PGA Tour and European Tour. He began his PGA Tour career with 22 consecutive made cuts, second only to Tiger Woods' 25-cut streak. Morikawa has six PGA Tour wins – including two major championships, the 2020 PGA Championship and the 2021 Open Championship, winning both in his debut. In May 2018, Morikawa spent three weeks as the top-ranked golfer in the World Amateur Golf Ranking. He also became the first American to win the Race to Dubai on the European Tour.

The 2021 Open Championship, officially the 149th Open Championship, was a golf tournament played 15–18 July at Royal St George's Golf Club in Sandwich, England. It was originally scheduled for 16–19 July 2020, but was cancelled due to the COVID-19 pandemic. It was the 15th Open Championship at Royal St George's, and the first since Darren Clarke won in 2011.
