Julio Giacomo Bonetti (July 14, 1911 – June 17, 1952) was a right-handed pitcher in Major League Baseball for the St. Louis Browns and Chicago Cubs. He is one of only seven Italian-born Major League Baseball players in history. Bonetti made his major league debut with the Browns on April 22, 1937. He became a versatile pitcher for the lowly Browns that season, pitching in 12 games out of the bullpen (notching one save) and starting 16 others, seven of which he completed. He managed just a 4–11 record and a 5.84 ERA, but his ERA was actually better than the last-place team's average of 6.00.
