After playing for the Waterbury team in the Connecticut State League in 1884, Lovett made his major league debut on June 4, 1885 for the Philadelphia Athletics. After pitching only 16 games, he did not pitch in the majors again until being signed by the Brooklyn Bridegrooms in 1889, when he helped the team to the American Associationpennant. Brooklyn jumped to the National League in 1890, and that year, Lovett was arguably the best player on the club. He went 30-11 with a 2.78 ERA. In the World Series, he pitched four complete games and won two of them, as Brooklyn played the Louisville Colonels to a draw.
Lovett then demanded more pay, and threatened to quit baseball.[1] He sat out the 1892 season, and when he returned, he was largely ineffective. He played in the minor leagues until 1896, after which he retired.
