Buffalo Bisons Conway began pitching in
Major League Baseball with the
Buffalo Bisons of the
National League in 1885. He made his Major League debut on August 10, 1885. One day after his Major League debut, Conway pitched his second complete game victory, this time against St. Louis. Conway allowed only four hits up to the eighth inning in the game. Two days later,
The New York Times took note: "Conway, Buffalo's new pitcher, is handling the ball very cleverly." Later that week,
The New York Times added: "Conway, Buffalo's new pitcher, is said to be a first-class man. He appears to be doing good work." At the end of September 1885, Conway lost a game against the Brooklyn Giants at the
Polo Grounds. Although Brooklyn won the game 11–2,
The New York Times again praised the effort of the young Conway: "With the exception of the second inning Conway pitched a good game, and was very effective. The support given him, however, was of the worst possible character, and allowed the local men to tally unearned runs with apparent ease." During the 1885 season, the 18-year-old rookie appeared in 27 games and pitched 26 complete games. As his debut came on August 11, his 26 complete games were thrown over a seven-week period in August and September – a remarkable average of almost four complete games per week. Conway compiled a record of 10 wins and 17 losses for a Buffalo team that finished in seventh place (next-to-last) with a 38–74 record.
Kansas City Cowboys After the 1885 season, the Buffalo franchise folded, and Conway signed with the
Kansas City Cowboys of the National League. Again, Conway played for a team that finished the year in seventh place, as the Cowboys compiled a 30–91 record. Conway appeared in 34 games for the Cowboys, 31 as a starter, and threw 30 complete games. He compiled a record of 5 wins and 15 losses. In his first full season in Detroit, Conway played on the
1887 Detroit Wolverines team that won the
National League pennant. Conway pitched 16 complete games and led the team with a 2.90 ERA, though his record was 8–9. Conway pitched four games in the
1887 World Series against the
American Association St. Louis Browns, winning two and losing two, as the Wolverines won the World Series 10 games to 5. Conway had his best season in 1888. He appeared in 45 games for Detroit and pitched 43 complete games and 391 innings. He finished the season with a record of 30 wins and 14 losses, and his winning percentage (.682) was the second highest in the
National League. During the 1889 season, Conway appeared in only three games for the Alleghenies. Though he won two of the three games, his earned run average soared to 4.91 – more than double his 1888 earned run average of 2.26. Conway appeared in his final Major League game on May 9, 1889. He was suspended without pay by the Alleghenies who claimed that he was not in condition to play. It was reported in the press that Conway had "snapped a cord in his arm," and that his "anterior detroid muscle was out of whack." The Alleghenies' suspension of Conway without pay following his injury sparked an early controversy over players' rights. In August 1889, newspaper accounts noted: "Pete Conway will be backed by the brotherhood in a suit against the Pittsburg club this fall. He was laid off without pay, but reports for duty, every day." In September 1899, Conway was reported to be using electricity on his arm to offset the effect of the injury.
Players' League In March 1890, Conway signed with the
Brooklyn franchise in the newly formed
Players' League. By late June, newspapers reported that he had been with the team for two months, but had not yet appeared in a game. A reporter quipped, "If he is drawing salary he is rather an expensive ornament." By the beginning of August 1890, it was reported that "Conway has not drawn a dollar from the Brooklyn club" and that he was "at his home in Philadelphia." ==Baseball coach==
