Scott Parsons, of Bethesda, failed to advance from the qualifying run of the single kayak event Sunday at the Lee Valley Whitewater Centre.
Parsons, a three-time Olympian, placed 16th with a score of 94.16, which left him 1.59 seconds shy of advancing along with the top 15. He was 10.91 off the pace of Germany's Hannes Aigner, who placed first with a 83.49 on his second run.
Casey Eichfeld -- who is from Drums, Pa., but worked at the Adventure Sports Center International in McHenry -- failed to advance in single canoe. He placed 14th, two places out of qualifying for the semifinals.
His first run, where he posted a score of 97.04, was the better of his two results, but it left him 6.48 off the leader, Michael Martikan of Slovakia, who had a 90.56 on his second run. Eichfeld's result was 0.97 away from 12th place, the cut-off for advancement to the semifinals.
