Kyle Thompson and Kevin Chappell share the halfway lead at the Cox Classic, an annual birdie fest that traditionally produces some of the lowest scores of the year. The pair stand 14-under par after two rounds at the Champions Run course but have very little breathing room heading into the weekend. Thompson posted a 6-under 65 early Friday to set the target score, which Chappell matched late in the day with his second consecutive 7-under 64.
