The current World No. 1, McIlroy reclaimed the top spot after the Farmers Insurance Open in 2020. He was last ranked No. 1 in 2015. The 1,605 days between stints at No. 1 is the longest in the world ranking’s history. McIlroy overtook Brooks Koepka, who held the top spot for 38 weeks. McIlroy has won four majors before his 26th birthday — the 2011 U.S Open, the PGA Championship (2012 and 2014) and the 2014 Open Championship.
