Fred Couples fires himself into the front of the Charles Schwab Cup Championship in the second round at TPC Harding Park. Fred Couples / Getty Images Fred had a bogey free second round -6 under par 65, to lead the Charles Schwab Cup Championship on -12 under par at the half way stage at TPC Harding Park. He emphasized that this was a big event, and he was here to win, despite something wrong with injuries to his neck and back; " This is a big event, these are the best players on the tour and I want to win. I'm certainly not playing any better because I want to win. I wanted to win at Birmingham, Seattle, Chicago, Newport and everywhere else I finished second. I had another good round and hit the ball well, when I hit pretty good irons I made the birdies. When you're near the lead, playing fast is a bonus. There's something going on, it's just not comfortable. It's doable, sometimes when I turn I snag it. It's more at night when I'm lying down. My back hurts and I don't sleep much. I wouldn't be playing if it hurt to swing. This is one of my all-time favorite courses, that helps me. As far as length, if I hit every fairway, I'll have an advantage all right, over my normal game." First round leader Peter Senior is in second place. his second round of -2 under par 69 giving him a tournament total of -10 under par, leaving him two shots off the pace. He said he did not do too much wrong, apart from missing some putts; " I didn't do much wrong, I didn't get away with anything but I think I'm in a good position. I had a heap of chances early in the round that I didn't convert." Bart Bryant is in third position after his second round of -5 under par 66,, for a -8 under par total. Bernhard Langer is another stroke back. and occupying fourth place alone after a -3 under par 68, for a -7 under par total. He is in a tussle with Kenny Perry for the year-long overall title, and the math needed to work out who is most likely at this point would need Einstein to work out. Kenny, who currently leads overall is in T11 position.
