In 1885, Tener, who was six-foot-four (1.93 meters), decided to try his hand at professional baseball. He joined the
Haverhill, Massachusetts, minor league baseball team in the
New England League as a pitcher and outfielder and was a teammate of future
Hall of Fame players
Wilbert Robinson and
Tommy McCarthy. Later that year, Tener made his
Major League debut with the
Baltimore Orioles of the
American Association, playing in a single game as an outfielder. While playing in Haverhill, Tener met his future wife, Harriet Day. They married in October 1889. After his brief appearance in Baltimore, Tener continued playing minor league ball, but also returned to the corporate world, working for the Chartiers Valley Gas Company in Pittsburgh and Chambers and McKee Glass Company. In 1888,
Cap Anson, the manager of the
Chicago White Stockings (now the Chicago Cubs), noticed him pitching in Pittsburgh and signed Tener to a contract. Tener was a pitcher and an outfielder for two years in Chicago with moderate success. He notched a 7–5 record with a 2.74 ERA in 1888 and went 15–15 with a 3.64 ERA in 1889. After the 1888 season, Tener accompanied the team on a world tour of Australia, New Zealand, Egypt, France, Italy and England. While in England, Tener was chosen to help explain the game of baseball to the
Prince of Wales, who would go on to become
King Edward VII. Tener was elected as Secretary of the Brotherhood of Professional Players, an early players union and served under President
John Montgomery Ward, a future member of the Baseball Hall of Fame. In 1890, unhappy with baseball's
reserve clause, Tener joined other players in jumping to the
Players' League. Playing for the
Pittsburgh Burghers, Tener compiled a poor 3–11 record. The league folded after one year and Tener decided to retire from professional baseball. He entered the banking business in
Charleroi, Pennsylvania, in 1891, becoming a cashier at the First National Bank of Charleroi. By 1897, he was the president of the bank. Over the years, Tener became a prominent business leader, founding the Charleroi Savings and Trust Company and the Mercantile Bridge Company. ==Political career==
