If you get caught out in front of a slider, YOUR SWING WILL LOOK LONG (beacuse you'll be trying to slow it down in mid-swing and your body will fly out and your arms will be left looping around) and if you're way late on a fastball...YOUR SWING WILL STILL LOOK LONG! (because now you're only 1/2 way through the swing when the ball is on you and it visually looks like you're late because your bat is slow or your swing is long).
Ya. To say nothing of looking off-balance on garbage swings.
:cpoints:
It says here that Smoak has one of the best swings in baseball, and the little tweak that he's used is IMHO most likely a sports-psych "reboot" button.
