He's 270 lbs and very athletic. That doesn't mean he's fast. He's still 270 lbs. I think Sano is speedier than Plouffe or Mauer but he's probably on par with a guy like Dozier... And they're both way slower than Buxton. In that situation, pinch-running was the right decision if the following got on base: a catcher, Mauer, Plouffe, Sano, Park, Arcia, Dozier. The increase in speed probably wasn't worth it if one of the faster guys was on base: Escobar, Rosario, Kepler, Nunez.
