SCOTTSDALE, Ariz. -- Play has started at the Phoenix Open after a four-hour delay because of heavy frost at TPC Scottsdale.

It was 39 degrees Thursday when the first round began at 11:40 a.m. local time.

Frost and frozen turf wiped out the pro-am round Wednesday and a frost delay is expected Friday morning.
