The reigning US Open champion, waited out bad weather that delayed the start of the second round at Colonial for 5 1/2 hours. “Really made the most of the round,” said Spieth, a back-nine starter who birdied four of the first five holes after making the turn.

“All in all, it was a fantastic (second) nine that we played.” American Webb Simpson fired a 67 to cling to the clubhouse lead at 8-under 132 with Spieth one shot adrift.

“It’s only halfway done,” Simpson said. “I’ve got a lot of work to do.”

Darkness halted play with 61 of 121 players still on the course and needing to finish their second rounds.

American Bryce Molder birdied five of the first eight holes but a double-bogey at the 12th hole left him on nine-under, only one ahead of Simpson with four holes to finish.
