Queen shot a two-under-par 71 over the more difficult La Manga South course to be lying joint seventh in Group A on 145 at the halfway point of the pre-qualifier. She had four birdies between the sixth and 13th holes.
Pretswell, still an amateur with selection for the Curtis Cup match in June a possible nice "consolation" if she delays turning pro, surged up from 30th to joint 17th in Group B on 147 after a par-matching 71 at La Manga North.
It was the proverbial game of two halves for Pamela - four birdies in reaching the turn in 31 but no birdies in an inward half of 40- which included a double bogey 6 at the 11th.
Former Scottish amateur champion Linzi Morton from Tulliallan - a professional caddie on the St Andrews Links Trust's "books," slumped in Group B to a share of 35th place with a 78. She struggled with 43 blows over the inward half.

Glasgow's Gemma Webster is alongside Morton on 151 with a 72 which was a mixture of six birdies and seven bogeys.
Former British women's amateur stroke-play champion Heather MacRae (Gleneagles Hotel) is well out of it - at the moment - in joint 64th place on 155 although she did improve to a 74 while Nicola Melville had a 79, also over La Manga North to be joint 96th on 164.
Back in Group A, Katy McNicoll from Carnoustie and Majorca-based Lauren Mackin have it all to do to reach the top 35 qualifiers over the next 36 holes. Katy is joint 56th on 154 after a second-round 79 while Mackin nosedived from a 72 to an 85 and a share of 69th place on 156.
