As Sunday's play begins at the 2012 PGA Championship in South Carolina, Rory McIlroy and Vijay Singh are the co-leaders at 6-under. Adam Scott is close behind at 5-under. It seems as though anything can happen at this point, as the weather-delayed third round will need to be completed before the championship round can even begin on the final day. It should be interesting to see how it all plays out.

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.
