Luke Donald lost the No. 1 spot in the World Golf Ranking in 2012 to Rory McIlroy and his career hasn't fully recovered.
Donald, now 92nd in the world, could win the Puerto Rico Open this week and still not qualify for the Masters, which takes the top 50 players plus a lengthy list of exempted players. A win wouldn't qualify Donald since the Puerto Rico Open is considered an "alternate event" to this week's WGC-Dell Match Play.
This extends a troubling trend for Donald, who had to qualify for the U.S. Open in 2015 for the first time in 11 years, after falling to 66th in the world.
In nine events this season, Donald has just one top-25 finish.
