There is a time for double switches and that was not it. In a game in which you were down 3 runs you can't take out your main power hitter that can turn around a game with one swing of the bat. It comes down to is it more important to get a 2nd innning out of Burton than lose 2 Dunn at bats. In a game in which you are down you need the 2 Dunn ABs.
