London (CNN) -- Young stars shone at the Olympic pool Monday as Yannick Agnel of France won his second gold medal of the London Games, American teen sensation Missy Franklin won her first and a 15-year-old Lithuanian stunned the women's 100-meter breaststroke field. The 20-year-old Agnel, just a day after swimming an amazing anchor leg in leading France to victory in the men's 4x100 meter free style relay, routed the field in the 200-meter freestyle. He beat both silver medalists, Park Taehwan of South Korea and Yang Sun of China, by 1.79 seconds. Ryan Lochte of the United States finished fourth.
