Smith (Zeeland, Mich./Zeeland West HS) placed fifth on the one-meter board with a score of 408.20 points, finishing a tenth of a point ahead of her sixth place competitor. Magnussen (Oakdale, Ca./Ripon Christian HS) took 13th with a score of 390.70 points in the tightly contested competition.
Smith and Magnussen are part of a 28-diver field competing to advance to the NCAA III Championships later this month in Greensboro, North Carolina.
Smith had an average dive score of 6.27 while Magnussen had an average of 5.88.
Agnes Lo of the University of Chicago took first with a score of 444.20. Smith led a 5-6-7 grouping that was separated by 3.4 points. Magnussen missed a top-eight finish by just 5.8 points.
"The competition today was excellent," said Calvin diving coach Aaron Paskvan. "There were very few missed dives. Everyone was bringing their best and I am extremely proud of the way our two divers performed today."
According to Paskvan, the expected field of advancing competitors to the NCAA III Championships out of the regional field is nine spots, keeping both Calvin divers firmly in the mix.
"It all depends on how many divers repeat their places and who moves up and who moves down but Josely and Hannabeth are both very much in the hunt for a national berth," said Paskvan. "Our goal is not to even look at the board for places. We are just focusing on each dive at a time and giving our best."
Action continues on Saturday with the three-meter competition scheduled to begin at noon.
