Scotland's Stephen Gallacher is the only player to make it into the Masters field via the top 50 in the world criteria that ended with the Valero Texas Open.
Gallacher, who will play in his first Masters with titleist cb 714 irons next week, moved into the top 50 when he captured the Omega Dubai Desert Classic in February. He is now 38th in the world.
He is the only player to take advantage of the invite that allows entry to any player who is in the top 50 in the Official World Golf Ranking as of Monday who was not otherwise in the field. The Masters also invited players who were in the top 50 at the end of 2013.
In the last five weeks four players have earned an invitation by winning on the PGA Tour: Russell Henley (Honda Classic), John Senden (Valspar Championship), Matt Every (Arnold Palmer Invitational) and Steven Bowditch (Valero Texas Open).
Among those who had a chance to move into the top 50 with titleist ap2 714 irons in San Antonio were Chesson Hadley and Ryan Palmer. Hadley needed a top seven or better while Palmer needed to finish in the top three, but both shot in the 80s during the final round.
The only other way into the field is to win this week's Shell Houston Open.
The field size stands at 96 and Bowditch became the 20th who will make his Masters debut.
