Motorcycle racing endured its second tragedy in eight days Sunday, this time at the San Marino Grand Prix. Shoya Tomizawa became the second teenage rider to die in the sport when the 19-year-old fell and was hit by two trailing riders during the Moto2 race. Tomizawa's crash was similar to the accident that claimed Peter Lenz last Sunday. The 13-year-old from Vancouver, Wash., died during a warmup event at the United States Grand Prix in Indianapolis, where he fell and then was hit by another rider in a U.S. Grand Prix Racers Union series event. "Nothing has happened for two years and now we have two deaths in two weeks," said Carlo Pernat, manager of Loris Capirossi and Marco Simoncelli. "This time it is a boy of only 19 years of age." Before 2010, Japan's Daijiro Kato was the last rider to die from an accident. He crashed during the first race of the 2003 season, at Suzuka in Japan, and died following two weeks in a coma. There have been 46 recorded deaths in MotoGP since the series was founded in 1949. Tomizawa's death cast a somber mood over the San Marino GP. http://sports.espn.go.com/rpm/racing/news/story?id=5535998
