In order to recieve this you will need to complete everything which includes the following:
-Complete the Tiger woods challange
-Complete one full year of tourny's and win each one (if you do you get a trouphy ball which you will need for the set)
-Lastly you will need to Collect the whole set of trouphy balls.
My suggestions would be to first complete the tiger challange with a created golfer and build up your stats which should be maxed out by the time you reach tiger and will make it much easier to do. After start up a season and breeze through that with your created golfer doing your best to get as many trophy balls along the was as possible. There is a list in your stats that will show you the ones you have and dont. Once you do this it should pop up.
Good luck, you will need it for some of the trophy balls :D
