Tennis takes center stage on the final day of the U.S. Open. The men's final between Novak Djokovic and Rafael Nadal will air at 5 p.m. here on CBS.
Don't be surprised if you hear a lot of grunts and groans during the match.
For tennis fans, all eyes are on the U.S. Open Monday night. The last major of the year attracts thousands of people every year, and tennis etiquette for both fans and players has changed over the years."When tennis was first introduced as a sport, it was really all about being proper. If you saw the outfits, the ladies wore long skirts, everyone was dressed in white, it was really a proper sport. As it has got more popular and fan-based, more of the issues that are coming is noise during the tournament," said Stephen Pike, General Manager of The Tennis Club of Rochester.
When it comes to the U.S. Open it's not uncommon for the crowd to get a little rowdy, but it's not just the fans making noise, it's also the players.
There's the famous grunt that most of the pros make during each swing.
"Mostly it's female players who grunt. A lot of it has to do with them getting in the rhythm with how they play. Grunting actually becomes part of their breathing pattern and exhaling as they hit the ball. It helps them with their rhythm and also it's been said in some studies that it helps females with their strength and core," said Pike.
And with only hours away until the championship, Monday night is sure to be an exciting one.
