Tiger Falters At Cog Hill

Jonathan Byrd has the lead after round one of the BMW Championship outside Chicago.

Byrd is at 7-under after firing off three straight birdies, and picked a good time to play his best round of the year. He's on the bubble for advancing to the FedEx Cup finale, at Number 30 in the playoff standings.

Tiger Woods is three off the lead at Cog Hill's Dubsdread course, where he won the Western Open three times.
