Isabelle Beisiegel opened with an even par round of 72 on the first day of the LPGA's final qualifying tournament.
Back-to-back birdies to start the back nine of the Champions Course helped Beisiegel of St. Hilaire, Que., recover from a pair of bogeys to leave her tied for 13th after the first of five rounds.
Stephanie Sherlock of Barrie, Ont., Rebecca Lee-Bentham of Toronto and Sue Kim of Langley, B.C., all opened with 1-over 73 to leave them tied for 37th.
Sherlock, who is back at Q-school after earning her playing card last year, finished with birdies on two of her final three holes to mitigate the damage done by five bogeys over a 10 hole span. Lee-Bentham, who came into the tournament fresh off her first professional victory at a Florida mini-tour event, finished with a bogey-double bogey on two of her final three holes. Kim had two bogeys and a birdie while playing her opening round on the Legends Course at LPGA International in Florida.
