Career
Born in Cincinnati, Boyle began his professional baseball career in 1886, playing in one game for the Cincinnati Red Stockings of the American Association. On November 12, 1886, he was traded (along with $350) to the Saint Louis Browns in exchange for Hugh Nicol. Jack caught only a couple of games until July 3.
An injury to the regular catcher, First Rate (at Lloyd's) "Doc" Bushong, gave him his opportunity.
He caught 87 straight games for the Browns using the old finger glove which preceded the protective mitt of the modern era. Boyle accompanied Charles Comiskey to the Chicago Pirates of the Players" League team in 1890, but returned with him to Saint Louis the following year.
In 1892 Jack signed with the New York Giants for a sum of $5,500. This was the largest salary ever paid to a major leaguer at this time.
There followed five years as a catcher for the Philadelphia club
On July 9, 1898, he was sold by Philadelphia to the Giants for $1000. However, he did not play a single game for them and was returned to Philadelphia on August 15, 1898. He also served as an umpire in the National League (4 games) and American Association (1 game) between 1888 and 1897.
He opened a saloon in the Ohio River city on Seventh Street which grew into a successful business for him.
Boyle was 46 years of age when he died of Bright"s Disease at his home on Academy Avenue, Price Hill in Cincinnati. He was interred at the Saint Joseph New Cemetery in Cincinnati.
