After earning 5,000 Player Points from beating GamerNet Challenges, you will earn this Achievement.
Player Points can be earned by selecting and defeating challenges in the EA Sports GamerNet menu or by defeating GamerNet Instant Challenges during regular play.
If you are playing a round of golf in another gameplay mode (Tiger Challenge, PGA Tour Season) when you surpass 5,000 points, the Achievement will not unlock until you return to the GamerNet menu.
