I think the logic would be that Gardy didn't want to lose his backup catcher, put Kubel in against a lefty or use Bartlett in any situation where he needed to utilize a bat.
Maybe Gardy thought he may have to pinch-run for Suzuki. Although Suzuki was on 1B with 2 outs and Mauer up, and he stayed in the game...
Also, maybe Gardy is in agreement with the folks who like Escobar better than Florimon vs LHP. Still, Florimon handled himself fairly well in his first two PA against Sale (no strikes missed or caught looking, worked the count full in his previous PA too) so it seemed a weird time to change course, for marginal benefit.
That situation pretty much screams for Pinto. He's more likely to get a hit, more likely to draw a walk, less likely to strike out, and FAR more likely to hit a HR than any of the other bench options, pretty much regardless of pitcher handedness. Wonder if Gardy would have approached it differently if the batter was the potential tying run?
Part of the benefit of playing a veteran like Suzuki (particularly one with a reputation as a durable gamer) is that it's less critical to always have a backup catcher available. If Suzuki gets dinged up, you're not risking your future to keep him in the game (where you otherwise might remove Mauer, Pinto, etc. for precautionary reasons). Basically, Suzuki shouldn't have to come out unless he suffers a catastrophic injury, so we should be able to deploy Pinto a lot more liberally, especially in the late innings. Swapping Bartlett for Hermann might be necessary here?
