Not that Darvish needed another pitch to put in his already crowded bag, but the extreme running fastball was an aspect of his game that I either failed to recognize and appreciate early on or had been unsuccessfully executed up to this point. I was fully aware that his fastball had plus-plus movement, but I’ve never seen a fastball with legs like that. From a scouting perspective, that’s easy 80-grade movement, regardless of what you call it.
