Jack Lynch (baseball)

John H. Lynch (February 5, 1857 – April 20, 1923) was an American Major League Baseball pitcher from 1881 to 1890. He played for the Buffalo Bisons, New York Metropolitans, and Brooklyn Gladiators.

His pitch selection included a drop curve and an "inshoot", which was probably the modern screwball.

The New York Clipper wrote of Jack Lynch:
 * Studying the in-and-out curves, rises, and drop deliveries, he rapidly acquired a reputation as an effective and puzzling pitcher...He has complete control of the ball, with all the curves and varying paces in delivery, and is cool and self-possessed.
