"It appears that MLB players are stealing 3B at a much higher rate"
ESPN did a lengthy analysis of the increasing number of steals of third base in MLB.
2005--327
2006--360
2007--368
2008--408
2009--415
2010--on pace for 445, as of 4/23/10
In 2009, the 415 steals came on 535 attempts--77.5% rate of success. The article didn't provide nos. of attempts in prior years--I don't know if the rate of success is increasing.
MLB has a surprising no. of 3B steals with two outs, with a high success rate.
