The Tommy Biershenk who stands 10 under at the midway point of the John Deere Classic doesn’t feel like the same player who missed his last six cuts. The change? An attitude adjustment that is paying big dividends at TPC Deere Run. The PGA TOUR rookie posted consecutive 66s -- marking just the second time he's shot back-to-back rounds in the 60s this year -- and Biershenk was three strokes off the lead when he finished on Friday. The Clemson grad's best finish this year is 50th at the Valero Texas Open but he's put himself in position for a much better result this week. "I told myself, Let's go out and have a little bit more fun," Biershenk said. "Certainly hitting it a little bit better and giving myself more opportunities and putting good. Getting it up and down when I miss the greens. The golf course is not that hard.  Hit the fairways and greens, there's a lot of birdies out there.     "My game is just better this week. That's what the difference is, as opposed to weeks leading up into here I was thinking too much and struggling a little bit. I've had fun the last few days. I'm going into the weekend with the same mindset. Going out to have a good time, have fun, and hit golf shots." Biershenk admitted it's difficult not to press when the results aren't there. He had an interesting round on Friday -- making just one par, two bogeys and eight birdies in his first 11 holes. A hot putter has been the key in the first two rounds, he used 25 in Thursday’s 66 and 27 on Friday. "You have to reminded yourself each week is an opportunity to change your life," Biershenk said. "I knew coming into this week I'd been struggling. Just got to keep my head held high and stay confident.  I knew my game was going to come around eventually.     "I'm start to go feel the old Tommy.  I'm starting to hit shots where I'm lining up at and certainly making the putts I need to make. Roundabout, my game is getting better and I'm staying patient.... "Feel pretty good about my game. It's a good feeling to finally put myself in contention instead of playing bad. ... Certainly a whole more fun to be playing good."
