Scott Langley is one shot ahead of a packed field in the Travelers Championship at TPC River Highlands. Scott Langley / Getty Images Scott returned a second round score of -5 under par 65 to lead the Travelers Championship by one shot at -11 under par. He carded eight birdies, a double bogey and a bogey in his second round at TPC River Highlands. Scott will not be thinking about any special possibilities that could be ahead; " I've been in contention, I played in the final group on Sunday at Memorial. This weekend, I'm not going to think about possibilities. I'm not going to think about what it means to win. I'm not going to think about any of that stuff. I'm just going to keep my head down and play my game." He was also annoyed about the double bogey; "I was ticked off because it was such an easy mistake, a simple wedge shot. I've given myself a lot of short birdie opportunities the first two days. Those are nice, when you start adding up three, four and five almost tap-in birdies, that just really kind of boosts you up." On this low scoring congested leaderboard Michael Putnam, Harris English and K.J. Choi are just a stroke back at -10 under par. Michael shot -7 under par 63, matching the best round of the day. Harris shot a 64, and K.J. a second round 65. Michael said his 63 could have been even better, but a three putt got in the way; "It was a perfect day for scoring. It left myself in some good spots and made a couple putts. I actually three-putted 13 for par so it could have been even better." The defending champion Ken Duke has a -3 under par tournament total, after a very sad +2 over par 72 second round, which kind of blew away his good round yesterday of 65; "I hit a lot of bad shots and I have no excuse for it, but yeah, it's good to finish strong and be here for the weekend. That's what you always want to do." The Masters champion Bubba Watson, the 2010 Travelers winner, followed his opening 67 with a +2 over par 72 to make the cut by a stroke at -1 under par. Looking at the scoring here so far I think the winner will have four rounds in the low 60's, it's just a case of How Low Can You Go.
