The Players Amateur is trying to get ahead of the weather.
Because of the threat of impending weather in the Friday forecast, the tournament committee has decided to play the first two competition rounds -- 36 holes -- on Thursday.
The second round will begin on the same tees as the first round, 30 minutes after the contestants sign their scorecards.
Should there be play on Friday, there is the potential for the tournament to end a day early on Saturday, rather than Sunday.

Also, according to McSwain, the players were notified upon registration that the tournament could be ended at 36 holes if the committee determines it is the best course of action.
