The U.S. Open is the final Grand Slam tournament of each tennis season, and 21-year-old Ethan Quinn can speak for every American when he says he loves being able to compete on home soil after a long year of traveling.But, of course, tennis is an individual sport, and each player in the tournament is battling to be the last one standing, including every American facing compatriots.Still, Quinn entering his third U.S. Open with his highest career ranking at No. 84 explained how tight-knit that group is despite the competitive environment.CLICK HERE FOR MORE SPORTS COVERAGE ON FOXNEWS.COMThe United States led all nations in main draw entries, with 30 players in the mens and womens singles fields combined."I think we all take a lot of pride in the fact that there are so many of us here," Quinn told Fox News Digital, while also discussing how important Orgain is in helping him meet his protein goals to stay in shape for such a demanding tournament. "I think this is one of the years where there are the most Americans in the main draw. We all take pride in that because it feels like a community."Before traveling to New York, Quinn competed at the Cincinnati Open the previous week. Though he wasnt able to make a run for the trophy, he said he loved seeing the camaraderie among his compatriots in the locker room.TAYLOR FRITZ BECOMES 1ST AMERICAN MAN TO REACH WIMBLEDON SEMIFINALS SINCE 2018"There were like six of us all next to each other, and its really fun when youre all together," he explained. "Its something I look up to with Reilly [Opelka], Taylor [Fritz], Frances [Tiafoe], and Tommy [Paul]. They all grew up together, they all know each other. Theyve basically known each other for 15 years. You look in the locker room and theyre best friends, and they all push each other. Theyre best friends, but when they play each other, they go all out because they dont want to lose.""They also want to be the best American. I know Taylor prides himself on being the number one Americanhe hates losing to other Americans. I, personally, hate losing to other Americans as well."As Quinn put it, beating "a lot of the Americans" means youre working your way up the ATP rankings, which is always good. Tournaments like the U.S. Open can also put budding stars like Quinn on the map for fans who dont follow tennis as closely throughout the year."I think being here at the U.S. Open is something were all really excited aboutsomething where we all want to push each other. We all want to be the last American standing. Its just a fun tournament. The environment is unlike any other in the world. Theres no other tournament that matches this energy," Quinn said.Quinn will begin his U.S. Open mens singles journey on Sunday afternoon against Switzerlands Jrme Kym. And while he knows he needs to look within himself to move on to the second round and beyond, he also knows he has fellow Americans in his corner."Tennis is an individual sport, so you usually have to just rely on yourself," he said. "Going through college, I was used to having a team. When you get to the pro level, you really have to figure out once you leave college, All right, whos my team? Having this many Americans who support each otherits kind of like our own little college team."Its something we all really appreciate. Its exciting, and its a fun way to go about our lives."PROTEIN PRIORITYFor a tournament like the U.S. Open, being properly prepared to make a run requires precise attention to things off the court as well as on.One of those is proper fuel, which Quinn thanks Orgains 30-gram organic protein shakes for. While he said he loves taking on dense meals, like smashing two burgers and a milkshake, having the convenience of Orgain has been something he cant go without during his season."Im a big believer in theres not too much protein [in your diet]," he said. "When Im fueling for dinner, Im having a big steak, Im having as much protein as I possibly can with what Im eating. But then, Im also having two Orgain protein shakes a day, especially when Im in a big training block. Leading up this week, Im on the road."Its been a chaotic week with obligations and obviously training, physios and everytihng like that. Having the convenience of just grabbing an Orgain protein shake its 30 grams of protein, five grams of BCAAs. Being able to grab that, get on the road and drink it on the way to the courts, its super easy. It tastes good. Its real food ingredients, so I know Im not harming myself. Im not risking anything, and I think thats my favorite part of it."Follow Fox News Digitalssports coverage on X, and subscribe tothe Fox News Sports Huddle newsletter.
