Vazquez threw from a three-quarters arm slot with "good command of a running/sinking fastball" that, according to FanGraphs, overall averaged 91 mph according to Josh Kalk of The Hardball Times was "over 93 mph on average" in his peak. Kalk considered this particularly impressive considering his arm angle noting that "normally pitchers who have a very low release point sacrifice speed and vertical movement for horizontal movement." Kalk went on to note that Vazquez's fastball averaged nine inches of vertical movement "thanks to an exceptionally high spin rate on his fastball."
