Teen star Ryo Ishikawa, of Japan, and Italian brothers Francesco and Edoardo Molinari were among 13 golfers who booked a trip to the 2011 Masters this week from the final 2010 world rankings.

The annual tee-off to the men’s major championship season at Augusta National Golf Club invites players who are among the top 50 in the world rankings at the end of the previous year.

Newcomers have boosted the field for next April’s event at Augusta National Golf Club to 92 players, with qualifying still possible by winning certain US PGA Tour events or reaching the top 50 in the week before the tournament.

Ishikawa, a 19-year-old prodigy, fired the lowest round on a major golf tour, a 58, in the final round to win the Japan Tour’s Crowns tournament last May. He has won eight titles in Japan but none outside his homeland since 2007.

Ishikawa jumped from 51st to 45th in the rankings on October 31 and stood 37th in the year-end rankings released on Monday.

The Molinari siblings, 15th-ranked Francesco standing three spots ahead of his brother, helped Europe defeat the United States in the Ryder Cup last October in Wales.

Joining them from Europe in reaching the Masters were England’s Ross Fisher at 33rd, Spain’s Alvaro Quiros at 49th and Swedes Robert Karlsson on 17th and Peter Hanson at 40th.

South African Charl Schwartzel, ranked 34th, and Americans Rickie Fowler at 28th and Sean O’Hair on 42nd also sealed their invitations to the Masters, which will be played April 7-10.

Australian Brendan Jones, ranked 55th, was the highest-ranked player not already on the Masters invitation list who failed to qualify on year-end rankings.

US star Phil Mickelson will try to defend the Masters crown at Augusta while former world number one Tiger Woods tries to end his longest major win drought at 10.

Woods has won four times at Augusta National but has not taken the green jacket symbolic of Masters supremacy since 2005.
