Even the most ardent golf fan would admit that sometimes tournament telecasts aren't exactly action-packed. The PGA Tour is trying to do something about that with its new iPad app, available just in time for this week's World Golf Championships-Cadillac Championship. The second-screen app compliments the live action, giving you shot-by-shot coverage of players or groups, all overlaid onto a graphic of each hole. On top of all the stats you'd ever want (drive length, distance to hole, etc.) the app even gives predictive stats, showing how likely Rory McIlroy is to make that 25-foot putt he's facing, for instance.
