Rory McIlroy is trying this week to win the European Tour Order of Merit at the age of 20.

It would put the Northern Ireland golfer second only to Seve Ballesteros on the all-time list if he does it.

Youngest-ever European Tour number ones:

19 - Seve Ballesteros (1976)

20 - Seve Ballesteros (1977)

20 - Bernard Gallacher (1969)

21 - Seve Ballesteros (1978)

21 - Sandy Lyle (1979)

22 - Sandy Lyle (1980)
