Former Ryder Cup winner Miguel Angel Jimenez has questioned the appearance of a 13-year old Chinese amateur in this week's Omega European Masters field at Crans Montana, Switzerland.

Ye Wocheng made history earlier this year when he became the youngest player, at 12 years and 242 days, to compete in a European Tour event when he qualified for the Volvo China Open.

Now Ye, who is a product of a youth program launched six years ago by the China Golf Association with the backing of HSBC, became the youngest ever to play on European soil.
