The second half of the PGA Tour 2012 Q-school got under way on Saturday, and we've got a new leader in Dong-hwan Lee. Moving up 16 spots with his 19-under mark, Lee finished the day 8-under, his best day thus far. Meen Whee Kim was the leader heading into the day, but he finished 17-under with a 1-over mark on Saturday.
A tie for second place with Kim rounds out the top five, as Edward Loar, Vaughn Taylor and Richard H. Lee all occupy that spot at 17-under overall. Other players with big games on the day include Michael Letzig, who finished tied for 10th, with a 6-under for the day and a 15-under overall, and Richard H. Lee, who was 8-under on the day, with a whopping 28 spots jumped.
Robert Karlsson, perhaps the most recognizable name in the tournament, had a poor day, dropping 15 spots and finishing the day at No. 17, tied with two others, and 3-over on the day (14-under overall).
With two rounds left, there's still plenty chance for some of the lower-ranked guys to punch their tickets into the 2013 tour. Round 5 will get under way on Sunday.
