I saw it out of the corener of my eye.

San Diego Steve sez:

If I'm working alone, and that call is my responsibiliy, the runner would have to leave mighty early, like 3 or 4 steps, before I would consider calling that. Why would the umpire be looking at anything but the pitcher. I was always taught to let the ball take your eyes where they need to be, so I'm focused on the baseball, and what Shifty McCheat is doing with that ball on the mound. If I see the runner take off with my peripheral vision, then great. Otherwise, I ain't lookin' for it.
