LPGA Tour officials made the unusual decision to play at least two rounds of the event on a golf course shortened to 12 holes because of the flooding caused by a foot of rain on Tuesday.
Par for the 12 holes being used at the Ocean Club course was listed at 45 and both Young and Cavalleri shot a 39.
The tournament was originally scheduled to be held over 72 holes, but now officials hope to play two rounds over the 12-hole course and then be able to use all 18 holes for the final round on Sunday.
Play was backed up by a weather delay Friday and there was not enough daylight to complete the round. The opening round will be concluded Saturday with the second round to follow.
