Bubba Watson believes golf should be celebrating the biggest hitters in the game – and he cannot work out why the sport is so "mad at that guy".

Without naming Bryson DeChambeau, Watson appeared to have his mind set on the likes of the man who leads the PGA Tour for driving distance this season.

DeChambeau, who is driving an average of over 320 yards, has faced some flak for placing such an emphasis on physical strength and building up his body to be more powerful off the tee. He plays with custom clubs, each of the same length, and is the defending champion this week at the U.S. Open, an unorthodox winner who rubs some up the wrong way.

Two-time Masters champion Watson, after moving into contention following the second round at Torrey Pines, used his platform to condemn what he sees as a culture of negativity towards players re-thinking the game and finding new ways to win.

"Truthfully, here's the sad part for me. I've got the microphone so I'm going to talk. The sad part for me is we celebrate every sport in the world. We celebrate accomplishments. We celebrate a guy scoring 50 points in the NBA. They are not saying quit shooting three-pointers. But we don't celebrate when a guy makes eight birdies or a guy bombs it 400 yards," Watson said.

"I don't understand how we're not celebrating. We're trying to make golf courses bigger, harder, dumber, however you want to word it, but we're not celebrating our great players.

"I'm definitely not in that group of great players. I'm saying I want to see these guys hammering the ball. I want the next up-and-comer. I want a 6ft 8in guy not playing in the NBA, I want to see him on the PGA Tour bombing the ball.

"We're the only sport not celebrating accomplishments of being a guy working out in the gym that can hit the ball miles. We're mad at that guy. I don't know why, but we are. I'm not, but some people are – golf course designers.

"The NBA, Tom Brady winning, throwing touchdowns, we celebrate that. They don't ever talk about us chopping out of the – hey, he laid up again. That's great. Anyway, that's my rant for the day."

Watson was offloading that baggage after adding a 67 to his opening 72 to reach three under, looking sure to be in contention going into the weekend as he sits just two shots behind clubhouse leader Richard Bland.

DeChambeau followed a 73 with a 69 to sit on level par, still in the hunt at five off the pace.

That was a far healthier position than Patrick Reed, Justin Rose and Jordan Spieth found themselves in.

Reed bogeyed his final hole to slip to three over, a five-foot putt brushing the edge of the cup. Reed won the Farmers Insurance Open at Torrey Pines earlier this year but was on the borderline of the cut mark after his round on Friday.

Rose added a 77 to his opening 78, and that meant the former champion had no chance of staying around for the weekend's action.

Three-time major winner Spieth followed an opening 77 with a gutsy 69 to give himself a slim chance of making the cut.
