Four players – Bernd Wiesberger, Anirban Lahiri, Paul Casey and Branden Grace–now have tickets to play at the Masters by virtue of their positions in the World Golf Rankings, further filling out the Masters field.

In the week prior to the Masters, everyone in the top-50 world rankings receives an invitation to play in the Masters at the famed Augusta National in Augusta, Georgia. The four players previously mentioned were the only ones still inside the top-50 in the world that had not already qualified for the event.

Lahiri, who is No. 33 in the world rankings, has had two European Tour wins this year at the Hero Indian Open and the Maybank Malaysian Open.

Grace, who is No. 41 on the list, was a winner at the Qatar Masters in January and will make his third start at Augusta following a 2012 – T-18 and a 2014 missed cut.

Weisberger is No. 42 in the world rankings. He became known last year to audiences in the United States with the impressive showing he had at the PGA Championship where he finished T-15 in the fourth and final major of the year. He became the first ever Austrian to compete at the U.S. open when he played last year missing the cut. This will be his first time in the Masters field.

Casey is No. 48 in the world rankings. The veteran stalwart on the European Tour made a commitment this year to play as a regular on the PGA Tour. He came close to winning his first Tour event since 2009 but lost in a playoff at Riviera in February. This will be his first trip to the Masters since 2012. In his eight previous appearances at the Masters, Casey has earned two top 10s, one T-6 back in 2004 and a T-10 during 2007.

Non-invitee players on the bubble failing to move into the top-50 included Marc Warren at No. 51, Harris English at No. 53, Alexander Levy at No. 57 and Andy Sullivan at No. 58.

At this point, the field for the Masters is currently 99. Should the Shell Houston Open winner this weekend earn a berth and if Tiger Woods announces he is playing, the field could be as big as 101. That would make it the first time since 1966 that the Masters has had a starting field in the triple digits.
