I'm interested in comments on this. You need to go to about 1:35 into the clip to see the whole thing (most of the clip is the Twins manager arguing with the umpire):

It looks to me like the pitcher had started to come set before the batter requested time and just stepped out.
Was the plate umpire correct in not granting time? (Looks to me like he was).
