The South Carolina weather has been fickle during the 2012 PGA Championship. The third round was delayed and will need to be finished before the fourth and final round can be played and a champion can be crowned. If the climate behaves, both rounds will be completed on Sunday.

The players are expected to be back out on the course at 4:45 a.m. PT -- weather permitting -- and will finish up their round. The fourth round is expected to begin at 8:30 a.m. PT.

The fourth round (and probably part of the third round) of the PGA Championship airs Sunday from 5 a.m. - 11 a.m. PT on TNT, then will switch over to CBS for coverage from 11 a.m. PT until the end of the day, however long that may take. You will be able to stream par-3 holes and cover marquee pairings live online at PGA.com. There is also a free PGA Championship app for mobile devices that will feature live video and leaderboard updates.
