Three-time major winner and gunning for a career Grand Slam this week at the PGA Championship in Bellerive, Jordan Spieth carded a 66 in the second round despite going out of bounds on the 17th and exhibiting some pretty understandable golf rage.Spieth's wholesome apple pie image belies a player who is never afraid to show his emotions on the golf course and who has to regularly rely on a magical short game to rescue him from some errant driving.All sides of his game were on display during a remarkable journey down the par 5 17th hole.After a wild tee shot that saw him find a lateral hazard on the right, Spieth found his ball after searching in some bushes, whereupon he angrily threw the offending object into the drink.The 25-year-old American then showed his genius by saving par with a stunning chip and clutch putt that preserved his momentum as he tried to remain on the coattails of the leaders.At -3 after two rounds, he is still someway off the pace being set at the head of the field by Gary Woodland, who added a 66 to his opening 64 to lie at -10.Indeed, Spieth voiced his frustration at the remarkably low scoring on a rain softened course that has seen players pepper the flags and record numbers not often seen in a major championship.Spieth felt the advantage of his short game was neutered somewhat by the forgiving conditions"I think that it's tough to come to a venue with bentgrass greens and this kind of weather. This course probably is phenomenal if it's not playing so soft. And it's not the rain that came on Tuesday, it was like that on Monday.

"You can just fire in and you get away with more, like you don't have to be as precise. That's frustrating in a major championship because typically what it does is you don't really have to be as precise on and around the greens. That's frustrating to me because I feel like that's an advantage that I have.

"So personally I would prefer more difficult and firmer, faster conditions on the greens. Having said that, I would have shot a much higher score yesterday, given you've got to be in the fairways in order to hold greens where they need to be.

"So I'm not saying that my score would be any better, I'm just saying what you would like to see in a major championship."

Thunderstorms delayed the completion of the second round for many of the competitors as the weekend promises another birdie barrage in Bellerive.
