Danny Salazar threw three curves in the major leagues before this year. Today, he threw two to Sal Perez. Here’s the second one, which froze Perez and allowed Salazar to steal a strike.

Considering that Salazar’s problems have mostly been in the command department, not the stuff section, a pitch that batters won’t swing at but can thrown into the strike zone could be a tremendous asset. At 82, with nice drop, it’s also going to be useful for whiffs and grounders — that’s one of the harder curves out there (would have been top 20 in velocity if it qualified last year), and that’s above-average drop, both good signs for a curveball.
