Bruce is right. With a smart and fast baserunner like Trout, you let him steal. With these average base stealers (Bourjos) you should stay on first and make the pitcher get out of the inning by pitching - not worth the risk most times. It has been proven that if a runner doesn't have over a 75% success rate of stealing bases, he is in fact costing his team runs. Trout was like over 90% last year I think, so no one should be mad with him running.
