That's because the Masters champ has made six bogeys and a triple bogey.
Robert Allenby has made 12 birdies and an eagle and he's six shots back. That's because he has made seven bogeys and a double bogey. He made six consecutive bogeys during his first nine holes in the first round.
Cabrera and Allenby show the wild range of possibilities at the TPC at Sawgrass Stadium Course.
It's why no lead seems safe here. Terrific charges and monumental collapses are both possible.
