DALLAS (AP) The final round of the AT&T Byron Nelson has started after a four-hour rain delay.

Hometown star Jordan Spieth, trailing co-leaders Marc Leishman and Aaron Wise by 10 shots, was in the first group off the first tee. Threesomes were going off both nines Sunday at the new Trinity Forest course south of downtown Dallas.

The Nelson is celebrating its 50th anniversary with a return to Dallas after 35 years at the TPC Four Seasons in suburban Irving.
