I agree, although I prefer to call it smart ball instead of small ball. I think the Blue jays were playing smart ball in May when they were winning so many games.
There is definitely an opposite to smart ball, which I will call dumb ball. For example dumb ball is:
1) Swinging for a home run with a man on 3rd and less than 2 outs in the bottom of the ninth or bottom of extra innings when the Blue Jays just need a run to win. Swinging for a home run usually doesn't result in getting a sac fly with hitters such as Gose and Rasmus - it usually results in a strikeout and the man eventually being left at 3rd base.
2) Players getting a green light on a 3 - 0 count and then swinging at a ball out of the strike zone.
I can only think of a couple for now, but if I watch a Blue Jays game I can usually spot several examples of dumb ball. There was one real head-shaker when John Farrell was manager - bottom of the ninth and the Blue Jays need 2 runs to tie so he gets the batter to sacrifice a baserunner from 2nd to 3rd (I think I remember it correctly?)
