You must be batting against a pitcher with the Wakefield or Nomo 
delivery type. When you get a man on first on second, get a big 
leadoff. Don't worry if he trys to pick you off, you'll make it 
back in time. When he doesn't try to pick you off, wait until he 
takes the step forward to begin his delivery. Now, quickly steal 
to second or third. He will not throw there and you will have 
plenty of time to get there. (NOTE: This trick works best in 
ROOKIE MODE, but you can still pull it off in Veteran and All-Star.
