Alfred Henry Spink, who saw Dunlap play, wrote that Dunlap could chase down a ball in the outfield and throw it to home plate "with such fearful speed and accuracy that the ball seemed to sing as it flew." Dunlap was known for his range in getting to balls that others of his era could not, and he was reportedly able to dive for a ball and throw while lying on the ground with enough velocity to sting the first baseman's hand. Dunlap was ambidextrous and was able to catch and throw a baseball with the same skill and accuracy with either hand. Moreover, Dunlap reportedly never wore a glove.
