Nelson delayed at least 3 hours after heavy overnight rain at already-soaked TPC Four Seasons

The second round of the AT&T Byron Nelson will be delayed at least three hours after nearly 5 inches of rain fell overnight on the already-saturated TPC Four Seasons.

The storm moved over the course starting about midnight Thursday after Steven Bowditch took a two-shot lead with an opening 8-under 62 that left Masters champion Jordan Spieth seven strokes off the lead in his hometown event.

The 4 1/2 inches from the latest storm pushed the total to about 17 inches in less than three weeks at the Dallas-area course. Texas officials are calling May the state's wettest month on record.

Spieth was set for an early tee time that will now be closer to noon Friday if not later as workers try to make the course playable.
