also, I just re-watched the Soler triple, and he hesitates for like a split second before booking it out of the box, he didn't cost himself a bunch of steps, and that reaction is instinctual to the flight of the ball too. But just in case we think it really does matter, a quick point of comparison. Using the broadcast, From the time the ball hits the bat to the time Kipnis receives the relay throw just into the RF grass was 13 seconds. For comparison, here's Tyler Naquin(an unequivocally faster runner than Soler) hitting an inside the park HR where he slides across at 16 seconds: http://m.mlb.com/video/topic/6479266/v1070372483/torcle-naquin-hits-insidethepark-walkoff-homer That means that even if we assume that Soler with 'hustle' is as fast as someone faster than him, that Kipnis has 3 seconds to get the ball to the plate. For comparison, for Soler to be safe in those circumstances would be like him beating the throw to 1B on a line drive to short that the SS drops right in front of him. Again, 0 percent chance of that happening.
