Israel's No. 1 swimmer Guy Barnea is the country's only realistic hope of winning an Olympic swim medal. The 20-year-old, who will participate in the 100 meter backstroke and butterfly competitions, should advance from the qualifiers to the semifinals if he approaches his Israeli record time of 54.90 seconds in the 100m backstroke. He also has a chance of reaching the final if he can slightly better his personal best, not a rare occurrence for athletes at the Games. Barnea, who trains at Berkley University in California, will be making his Olympic debut in China. At this year's European Championships, he finished seventh the 100m backstroke final.
