SPRINGFIELD, Ill. (AP) — Christina Kim shot a 9-under 63 to take a one-stroke lead at the State Farm Classic, a tournament she just missed winning last year. Last year Kim birdied 18 to momentarily tie Sherri Steinhauer at 16 under, but the veteran Steinhauer matched Kim on the last hole to win.

The field was stacked with low scores, including a 67 from Michelle Wie that was her best of the year for the part-time golfer and full-time Stanford student.Wie, playing on a sponsor's exemption, and most of the lowest-scoring golfers teed off early in the morning, before temperatures neared 90 degrees.
