I mentioned upthread, but I don't consider Robinson to be a generically "weak hitter". This is basically his third full season in MLB, and he has been just under the league batting average in all three. The power leaves something to be desired, which is why pinch hitting with Hunter might have been a good play, but in terms of getting a hit, Robinson is not Butera, Fryer, 2015 Herrmann, or a pitcher up there. His likelihood of simply getting a base hit is about equal to Hunter and Dozier. Actually, I could see some argument that letting Robinson hit instead of Hunter makes Toronto prepare for a possible bunt, and maybe reduces the chance of a DP, without losing any likelihood of a simple base hit. But I don't think actually making him go through with the bunt, on the first two pitches, the second of which was way out of the zone, was a good idea in that situation. Also, if Hunter is no longer viewed as a good hitter in that situation, and is ceding more starts to Robinson... maybe there actually is room for another outfielder/bat to get playing time?
