By Chris Reimer, PGA TOUR staff KUALA LUMPUR, Malaysia -- Scott Piercy opened the CIMB Classic with a disappointing 75 and was tied for last place following the first round. Piercy admitted he wasn't hitting the ball well that day, but suggested that traveling overseas for the first time in his life and learning to deal with the effects of jet lag might have had something to do with his 4-over round. "I had a little trouble trying to figure out what my body was feeling. I woke up in the morning and up for a couple hours and the clock says 8 in the morning, but my body felt like it was 5 at night," said Piercy, who won the RBC Canadian Open earlier this year. "I figured something out in my swing that helped and as the week went along it got better. I got confident the more I saw the ball going in the hole and the more I saw the ball going where I was looking." Following his 75, Piercy went right back out to the driving range on Thursday despite the high temperatures and think humidity. The work paid off as he battled back with improving scores each day. Piercy shot 68 and 64 in the second and third rounds, respectively. A course record-tying 62 in the final round moved Piercy into the top 10 at 15 under. "I hit 18 greens today and could have even shot four or five strokes better, easily. I think it was a combination of swinging it poorly, jet lag, understanding the course. I found a good swing thought, learned to trust it out there, got acclimated to the time change and it all came together today," Piercy said. "I probably won't win the golf tournament. You never want to come over here and finish last. I like it over here and can't wait to come back."
