After two rounds of The Senior British Open Bernhard Langer and Mark Wiebe are tied at the top of the leaderboard at Royal Birkdale. Mark Wiebe / Getty Images Mark managed to bogey the sixth hole for the second time in as many days, but still carded a second round - 5 under par 65, to share the lead with Bernhard Langer, on the par 70 Royal Birkdale layout. Mark said he was tickled to shoot a low round, and be where he is; "I really got my irons zoned in on the back nine, I know there's a long way to go, but I'm tickled to be where I am. It was unbelievable and great to shoot the low round." Bernhard, the 2010 champion at Carnoustie, shot a second round -3 under par 67, for his total of -5 under par, which included a two stroke penalty for double hitting the ball. Apart from that misdemeanor Bernhard said he had played great golf; "The ball was sitting up in the long grass and I caught it high on the club face and again on the follow through, but that was my only blemish. Most of it was impressive and good, and I putted a little better today." David Frost , repeated his first round score of -2 under par 68, and is just a stroke back in third place. He said it was his putter that saved a shaky round; "It was a bit of a shaky round, I didn't feel comfortable with the club in my hand. I hit some wayward shots, but managed to hit good irons into the greens and the putter was my savior." Tom Watson, only got going after a very indifferent front nine, which featured two birdies, two bogeys and a sad double-bogey. Tom then converted long putts at Nos. 11, 12 and 13 and sunk another birdie putt at the 15th hole. He unfortunately bogeyed the last two holes of the day to finish in a group on +4 over par. The overnight tournament leader Gene Sauers could manage an even par round fo 70 today, which left him sharing fourth place at -3 under par. He admitted he did not play so well in the second round, but was pretty happy with where he was at this stage of the tournament; "I'm happy with where I am. I didn't hit the ball as well as I did yesterday and I didn't putt as well either."
