Luke Donald finally led the Byron Nelson Championship after all his under-par rounds in the event.

Donald's 4-under-par 66 yesterday in Irving, Texas, was his 10th straight Nelson round in the 60s and put him at 7-under 133 through two rounds, a stroke ahead of defending champion Brett Wetterich (68), Fredrik Jacobson (67) and first-round leader Sean O'Hair (69).

It's the first time Donald has led at the end of any round at the Nelson, where 16 of his 20 career rounds over six tournaments have been under par.

Kent Jones (66) and Scott Verplank (68) were two strokes back, and Vijay Singh (67) was in a group of five players at 4 under.

This is the first time the tournament has been played without Byron Nelson, the champion golfer known as "Lord Byron" and in 1968 the first to have a PGA Tour event named after him. He died Sept. 26 at age 94.

Donald took over sole possession of the lead with a 43-foot chip from the edge of the green at the 196-yard 17th. That was a hole after he missed his only fairway and had to settle for par at the 554-yard 16th, the easiest at the TPC Four Seasons.
