Chiefs point to Monday finish after heavy rain

US OPEN officials believe a Monday night finish is a distinct possibility after torrential rain washed out the opening round at Bethpage Black.<br /><br />Play was suspended after just three hours 15 minutes following sustained heavy rain in New York, before a complete halt was called around 2pm local time. Half of the 156-man field had yet to start their first rounds with the opening groups only having completed 11 holes.<br /><br />With heavy rain also forecast for today, and even tomorrow, the second round is also likely to be heavily disrupted, leaving officials with a major headache going into the weekend with the United States Golf Association reluctant to declare a champion until 72 holes have been played.<br /><br />World No3 Paul Casey is currently two shots off the four-way lead on one-over-par after five holes, and says the eventual champion will need plenty of patience. &ldquo;It&rsquo;s only going to get worse but we will see what happens,&rdquo; the British No1 said. &ldquo;You are certainly going to have to strike the ball very well but it&rsquo;s going to be the guy who keeps his head this week.<br /><br />&ldquo;That's going to be very difficult and you are going to have be patient and expect some difficult lies and some mud-balls. That&rsquo;s the way it is.&rdquo;<br /><br />World No1 Tiger Woods was also one-over after six holes.
