JACKSONVILLE, Florida (AP) ― Ernie Els and Retief Goosen enter the 2012 season without any assurances of playing in the Masters.

The field for the Masters took shape Monday after the final official week of golf tournaments around the world. Among the criteria for an invitation is to be among the top 50 in the world ranking at the end of the season.

Els fell to No. 56 in the final ranking. Els has been eligible for the Masters every year since his debut in 1994. Goosen, a two-time U.S. Open champion, is at No. 53. Jim Furyk narrowly claimed a spot in the Masters, to be played April 5-8, when he finished at No. 50. Furyk began the year at No. 5 in the world.

Others who got into the Masters through the world ranking were Ian Poulter, Paul Casey, Alvaro Quiros, Kim Kyung-tae, Simon Dyson, Bae Sang-moon, Rickie Fowler, Francesco Molinari, Miguel Angel Jimenez and Gonzalo Fernandez-Castano.
