Professional golfer Hayden Springer shot -6 at the Rocket Mortgage Classic qualifiers. This was good enough to make it into a four-way tie for a playoff, with spots in the upcoming PGA Tour event up for grabs. However, in a rare instance, the golfer was not eligible for the playoff because he told on himself.Springer actually began competing in the playoff with three spots available in the Tour event and four golfers vying for them. However, at that moment, he realized there was an extra club in his golf bag.Tony Paul@TonyPaul1984The Rocket Mortgage Monday qualifier at Fieldstone went to a playoff — four players for three spots.

Sad story.515The Rocket Mortgage Monday qualifier at Fieldstone went to a playoff — four players for three spots. It was over on the first hole when one of the four, Hayden Springer of Texas, accidentally had a 15th club in his bag. Two-stroke penalty, and that was that. Sad story.Under USGA Rule 4.1(b), all golfers can have up to 14 clubs in their bag. That's what Springer had initially, but he had been practicing before the playoff with a different club. In an honest mistake, he forgot to take the club out.When he realized what he'd done, he admitted to his mistake, knowing it could cost him. As noble as that was, it couldn't be ignored and Springer got a two-stroke penalty. As a result, he was ineligible to play in the playoff and thus not able to qualify for the Rocket Mortgage Classic.Even after the penalty, Springer had a chance to extend his life. He had to nail a putt for birdie, which might have kept him alive a little longer. However, he missed and ended up with a double bogey and lost out.Kevin Helm, Executive Director of the Michigan Section PGA, said:"It's great integrity. Nobody else knew. Kudos to him. He noticed it. He didn't think to take it out of the bag."It cost him a spot on the next PGA Tour event, but he did the right thing and was widely commended for it.Who did make the Rocket Mortgage Classic?While Hayden Springer missed out because of his honesty, Andy Spencer, Peter Kuest, Kyle Reifers, and Brett Stegmaier made the Rocket Mortgage Classic field through the qualifiers.They will join the following top PGA Tour stars this weekend (with odds to win it):Tony Finau +1200Rickie Fowler +1400Justin Thomas +1400Collin Morikawa +1400Max Homa +1800Hideki Matsuyama +2000Tom Kim +2200Sungjae Im +2200Keegan Bradley +2800Cam Davis +3500Harris English +4000Brian Harman +4500Sepp Straka +5000Chris Kirk +5000Tom Hoge +5500Stephan Jaeger +5500Byeong Hun An +5500Taylor Moore +6000Patrick Rodgers +6000Nicolai Hojgaard +6000Ludvig Aberg +6000Christiaan Bezuidenhout +6000Alex Smalley +6000Justin Suh +6500Davis Riley +6500Joseph Bramlett +7000Brendon Todd +7000Brandon Wu +7000Beau Hossler +7000Adam Hadwin +7000Can Tony Finau win the Rocket Mortgage Classic?It is a pretty deep field with a lot of excellent golfers.
