Beat all 21 games in the Play Now feature to unlock Tiger's shirt. When you play with the red shirt Tiger, his in-game stats will match his actual real-world stats, giving him a major advantage.

While playing a game against one or more human opponents, press SQUARE, CIRCLE, TRIANGLE or X to taunt the golfer while he is at the tee box. You will hear golf-related sounds (a ball dropping in the cup, crowd noises, etc.) each time you press a button. Hold down R1 or R2, then press the SQUARE, CIRCLE, TRIANGLE or X for even more annoying sounds.

Bear in mind, though, that you are a knavish cad if you do this.

To make a CPU player's turn go faster, hold L1 and TRIANGLE to fast forward through it.
