The obvious thing to keep an eye on is Alex Cejka's score. I'd put the over-under at 75, and recommend you take the over.There is no one in golf I'd rather watch swing the club than Angel Cabrera. When he gets it going he makes the game look absurdly easy, and even with the humidity I'm not sure Cabrera broke a sweat during his second-round 65. I wouldn't be surprised to see him take it deep on Saturday and wind up with the lead heading into the final round.All that said, what I'll really be watching on Saturday is Ian Poulter. At the Ryder Cup he summoned one of the gutsiest performances in ages and I thought it would begin his ascension into an elite player. He hasn't done much since but this Players represents a huge opportunity: to win for the first time in the U.S., to win for the first time anywhere in three years, to win for the first time against an elite field. Poulter proved at Valhalla he has the stones to get it done under excrutiating pressure. Now he needs a solid third round to put himself in position for a breakthrough victory.
