Michael Sim announced Friday that he has withdrawn from the Masters due to an injured shoulder. The injury had kept the 25-year-old Australian out of action since his 68th-place finish at the WGC-CA Championship at Doral last month.
Sim earned his spot in the field at Augusta National, as well as his full-time playing privileges on the PGA Tour this year, by virtue of his record-breaking 2009 campaign on the Nationwide Tour. He is currently No. 43 in the world rankings.
Sim started the 2010 season in strong fashion with a runner-up finish to Ben Crane at Torrey Pines in January, but has struggled since. This was to be the first time playing in the Masters for Sim, who finished T-18 at the 2009 U.S. Open at Bethpage in his first appearance in a major championship.
It's been a busy couple days for players withdrawing. Both Paul Casey and Vijay Singh pulled out of the Shell Houston Open on Thursday. However, neither has ruled out playing at Augusta yet.
Since there are no alternates at the Masters, Sim will not be replaced in the field. The number of qualifiers is currently at 97, but that number could increase by one depending on who wins this week in Houston.
