Two-time U.S. Open champion Bryson DeChambeau was hailed by United States teammates as an explosive X-factor, gladiator and showman on Tuesday as controversy erupted around him at the Ryder Cup.

It began when the 32-year-old LIV Golf star, whose interview session at Bethpage Black was postponed to Thursday after the opening ceremony was advanced to Wednesday, fired the latest verbal salvo in a war of words with Europe star Rory McIlroy.

"Just his golfing ability alone is an X-factor for our team, but also, he's a really fiery player," U.S. captain Keegan Bradley said of DeChambeau.
