Singh had 27 points under the modified stableford scoring system used in this event, giving him a 4-point lead over Steve Flesch.

For the second straight day, lightning and rain invaded Castle Pines Golf Club. After causing a 2-hour, 40-minute delay on Thursday that forced 36 players to finish their rounds early yesterday, lightning struck again with half the field still on the course.

Singh, who began the day as the co-leader with Jim Carter at 15 points, added 12 points to his total tying the 36-hole tournament record set by defending champion Phil Mickelson last year.

Brandt Jobe finished with 22 points and Jesper Parnevik had 21. Davis Love III was at 20.
