Re: What exactly is "extended spring training"?
HHF had a good reply - plus a lot of times they aren't really "games" in the truest sense of the word - the clubs set up bizarre situations. Like if they want a guy to get some at bats in, they may have him bat first every inning. Or they may allow 5 outs in an inning to get the D some work in.
I went to one of the Angels one a couple of years ago and they had a pitcher bat first three innings straight and he bunted every time.
