In only his second start as a major leaguer, Jake Thompson took the mound against the Colorado Rockies and, despite the mathematical issues that make such an accomplishment improbable, proceeded to record four strikeouts in a single inning, becoming the first Phillies pitcher to do so since 1902. To execute such a feat, Thompson took advantage of an archaic and confusing baseball rule that, for the benefit of the reader, may be loosely translated as follows:
If, with two strikes in the count, a batter proceeds to swing at a pitch so far removed from the strike zone that it is not only unhittable, but uncatchable by the very player whose designation is to catch the baseball, then the batter may commence as if he, by virtue of his own skill, put the ball in the actual field of play.
The seemingly inane rule allowed us to witness a pitching event that occurs more infrequently than the much celebrated no-hitter. But more relevant to the author’s intentions, it has given us a pretense upon which to discuss the pitch not only directly responsible for the rule’s enforcement, but also largely instrumental in the consequent four strikeouts. That is, Jake Thompson’s slider.
