You are assuming the pace stays at -7, which it probably won't as scores will be higher today. Keep in mind that there are only 113 golfers in this event and the top 70 plus ties make it, so she only has to beat about 35 of the men to make the cut. Right now, she is ahead of 27 of them. That being said, I still think it will be very difficult for her to make the cut with conditions being a little harder today. Good luck to you whichever way you go, but at -300, that is probably a tad high.
