PGA Championship 2016 Leaderboard: Live Updates, Storylines to Watch for Sunday

Sunday figures to be a long day at the PGA Championship at the Baltusrol Golf Club in Springfield, New Jersey.

After the majority of the field was unable to play Saturday because of rain, most players will try to play 36 holes Sunday in an attempt to determine the winner of the last major event of the golf season.

However, it may not be a matter of players muscling up and playing two full rounds Sunday. Weather.com forecasts more rain, and if the precipitation is significant enough to warrant another stoppage in play, the Wanamaker Trophy may not find an owner until Monday.

One of the top stories involves defending champion Jason Day, who put himself in a position to challenge second-round co-leaders Robert Streb and Jimmy Walker when he fired a five-under 65 Friday. Day appeared to be on his way to a frustrating round when he had a double bogey on the seventh hole that left him at even par, but he responded with birdies on seven of the next eight holes.

Day was just two strokes behind the leaders as the third round got underway, and he moved into a tie for the lead by 9 a.m. ET, as the co-leaders had both dropped a shot through the first five holes and the Australian superstar was one under.

Another top story centers on Streb, who was sensational Friday when he fired a 63. While he is not one of the more well-known players, he excelled on the big stage during the second round. However, it's quite another thing to come through in the third and fourth rounds of a major championship. 

Streb ranks 112th in FedEx Cup points and is the 74th-ranked player in the world. He has made the cut in just 14 of 23 events this season and has earned slightly more than $665,000 this year. If he can remain in contention throughout the final two rounds of a major championship, it will be the most significant performance of his career.

British Open champion Henrik Stenson is capable of getting the best of any field. He did that two weeks ago at Royal Troon while being challenged by Phil Mickelson, and now he is in contention at Baltusrol. Stenson had fired a pair of 67s in the first two rounds and was one under through his first seven holes of the third round.

He's in a position to challenge for back-to-back major championships.

Stenson's win in the British Open was the first major championship of his career, and back-to-back wins in the British Open and PGA Championship would put him in the driver's seat when it comes to claiming Golfer of the Year honors.

While there's still a long way to go in that race with the FedEx Cup playoffs coming up, winning two major titles in the same season would be a big statement for Stenson.

Talented young golfers Emiliano Grillo (23) of Argentina and Hideki Matsuyama (24) of Japan could both write dramatic stories if they can remain near the top of the leaderboard throughout Sunday. Grillo was even par through six holes in Sunday's third round and six under for the tournament.

Matsuyama, who has one tournament win this season along with five top-10 finishes and has earned nearly $3 million, was five under after nine holes Sunday. He is one of the best players when it comes to wedge play, ranking third in shots gained on approach shots, according to PGATour.com.

Lastly, don't count out Martin Kaymer, who has not been active this year but finds himself in contention at four under through his first seven holes Sunday.

Kaymer won the PGA Championship in 2010 and the U.S. Open in 2014, so he is capable of winning on the biggest stage. If Kaymer can hold it together through the first three rounds, he should be able to handle the pressure in the final round.
