NEW YORK -- On the eve of this tournament, most people thought we would be getting the eighth installment of the Grand Slam final rivalry between Novak Djokovic and Andy Murray.But Kei Nishikori had other ideas, beating Murray in a five-set quarterfinal before the Japanese No. 6 tired down the stretch in the semis against Stan Wawrinka.Djokovic has done his part, albeit with a lot of help from his ailing opponents, and is 19-4 against Wawrinka. But dont expect this match to be as lopsided. The Swiss has stunned Djokovic twice at majors, including last years French Open final, and you can expect a heated competition in what will be another muggy day Sunday at the US Open.

But Djokovic has had to complete only 13 sets on his way to the final and has played just 118 games. Wawrinka on the other hand? He has played 23 sets and 237 games. Djokovic should have plenty of reserves. Theres also the small matter of him being the best player in the world -- the one who is well-positioned at 29 years of age to surpass Roger Federers record of 17 majors.The case for Wawrinka?The 31-year-old from Switzerland is the ultimate big-match player -- he has won both of his two Grand Slam finals, taking out the No. 1 player in the world at that time on each occasion. He advanced past Rafael Nadal at the 2014 Australian Open (beating Djokovic in the quarterfinals). Then came Wawrinkas astonishing, four-set win against the Serbian at Roland Garros last year. Wawrinka has plenty of reason to be optimistic he can pull off another upset, not the least of which is Djokovics physical state. Although Djokovic is fresher, he has needed treatment for wrist, elbow and shoulder injuries at this US Open. Wawrinka showed impressive mental and physical strength to come back from match point down against Britains Kyle Edmund before beating resurgent fan favorite Juan Martin del Potro. Wawrinka then outlasted Nishikori in brutally humid conditions in Arthur Ashe Stadium on Friday night.Prediction: Djokovic has been the favorite with the bookmakers to lift the title here from Day 1. It seems crazy to ever doubt the world No. 1 at any tournament, but Wawrinka has big-match DNA. Wawrinka in five spectacular sets. Custom Kansas City Chiefs Jerseys .

LOS ANGELES -- Coach Clay Helton doesnt think Southern California has a whole new offense under quarterback Sam Darnold. Just one with another threat.The mobile freshman has unlocked the run-pass option for USC, adding another wrinkle to the Trojans offense. Thats created space for wide receivers and running backs, something Helton hopes will continue against No. 21 Colorado on Saturday.You have two runners in the backfield, one at the quarterback position, Helton said Tuesday. They are having to load the box and now you are having some man-to-man coverage outside.Darnold has taken advantage of those looks, throwing for 352 yards and three touchdowns without an interception against Arizona State in a 41-20 win Saturday. He also rushed for a touchdown in that game, and Darnolds presence helped senior Justin Davis run for 123 yards and a touchdown.Davis likes that defenses have to account for Darnold as a runner, and likes it even more when a defender drops him in the backfield for what would have been a 2-yard loss only for Darnold to keep the ball on a read-option.I look up and Sam has the ball, Davis said. You dont know how happy that makes me, just to see that they have to worry about him carrying the ball. Just to have someone like that, Im loving it right now.After rushing for a total of 135 yards in USCs first three games, Davis has 249 yards in the last two with Darnold at quarterback. Davis had a 50-yard run against Utah and ripped off gains of 49 and 37 yards against Arizona State.Darnold had 41 yards rushing in his first career start against the Utes, giving Arizona State something to account for..dddddddddddd. But offensive coordinator Tee Martin said many of Darnolds gains on the ground are improvisation, including his touchdown run against the Sun Devils.And when USC does call a designed run for Darnold, his ability to adjust can result in big gains through the air. Darnold pulled up on a busted quarterback draw and found sophomore Deontay Burnett for a gain against Arizona State. Helton credited Darnolds experience as a point guard in high school for his quick decision making.We had a physical beat inside, he bounces off and somehow catches a little peripheral vision of Deontay out there, Helton said. Guess he had to do it a lot, and its showing.There is still work to do refining the run-pass option part of the offense. Darnold said USC left a lot of yards on the table against Arizona State because of available screen passes he did not throw.Helton is pleased with the steady progress Darnold is making as both a runner and a passer, and that extends to the entire offense when it has the balance between the run and the pass USC displayed against Arizona State.The marriage between the two is the reason we are successful, Helton said.And as long as the Trojans are running for nearly 200 yards per game, Helton is fine with any description of his offense. His quarterback, however, agreed with Colorado coach Mike MacIntyre, who said the Trojans have changed their entire offense in the past two weeks.I guess were a spread if you want to put it in literal terms, Darnold said.
