HUMBLE, Texas (AP) -- Angel Cabrera and Carl Pettersson each shot a 7-under 65 on Thursday morning to set the pace in the Houston Open before the first round was suspended due to bad weather.
Only 51 players completed their rounds before thunderstorms rolled across Redstone in the afternoon. The tournament had not been delayed by inclement weather since 2009.
Defending champion Phil Mickelson, Fred Couples and Ernie Els, who needs a victory to qualify for next week's Masters, were still playing their front nines when play was suspended.
The first round will resume at 8:30 a.m. EDT on Friday.
Ricky Barnes and Jeff Maggert completed their rounds and were one shot off the lead. Brian Harman also was 6 under, but had three holes left in his round.
