You can read the full list here from Darren Rovell but here are some I found interesting:
3. Lacrosse is the fastest growing sport in America. There were 1.6 million people who played lacrosse last year, a 37.7 jump. Lacrosse participation is up 218.1 percent over the last 10 years.
4. An amazing 60 percent of people that play soccer outdoors are under the age of 18. Outdoor soccer is the second most popular sport for kids under the age of 13 after gymnastics. However, in the much talked about disconnect between playing and watching, only 20.5 percent of those who play outdoor soccer are really into Major League Soccer.
5. In 2010, almost twice the amount of Americans played basketball (26.3 million) over baseball (14.5 million). Baseball participation was up 5.2 percent in 2010, but still down 8.1 percent over the last decade.
7. Volleyball has the most amount of female participants (9.1 million), followed by soccer (6.8 million), basketball (6.5 million) and softball (4.7 million)
