from 1908 to 1910. His most notable game from that period may have been a three-hit, thirteen-inning win on Opening Day 1909; opposing pitcher Red Ames had a no-hitter going into the tenth inning. In his three seasons with Brooklyn, he registered a 22–42 record. Wilhelm was back in the minor leagues with Rochester in 1911. In three seasons with Rochester, he won 48 games and lost 24 games. Before the 1914 baseball season, Wilhelm was signed by the Baltimore Terrapins of the Federal League (FL). In 1915, the new Colonial League emerged with backing from the FL. An agreement between the leagues provided each Colonial League team with six FL players; the FL received $200 per month for each player sent to the new league. When ordered to the new league by FL officials, Wilhelm refused to report. Instead, he was made an FL umpire. In 1916, Wilhelm sued the Terrapins on the grounds he had signed a three-year contract in 1914 worth $10,500 and was not allowed to continue with the team after July 1, 1915. Wilhelm spent the 1916 and 1917 seasons with the Elmira Colonels of the New York State League. In those two seasons, he finished 14–19 and 17–16 respectively. Wilhelm pitched for the Jersey City Skeeters of the International League in 1920. That year he was the winning pitcher of both games of a doubleheader, leading the team to 7–3 and 10–0 wins. Wilhelm became manager of the Philadelphia Phillies during the 1921 season. In early September, The New York Times criticized Wilhelm's team after losing both games of a doubleheader, saying that "Every day is Labor Day for the Phillies... The Quakers were in perfect stride during both contests and demonstrated they can lose as easily and dexterously on a holiday as on any other occasion." Wilhelm had become the interim manager earlier in the season after Wild Bill Donovan was called as a witness in the trial surrounding the Black Sox Scandal. Wilhelm was discharged from his position in late 1922. Wilhelm's managerial record was 83–137 in Philadelphia, which included 96 losses in 1922. In 1923, Wilhelm made his final professional appearance as a player, taking part in a single game with the Rochester Tribe. In the summer of 1928, Wilhelm took a position as scout for the Montreal Royals. Wilhelm died in 1936 and a benefit minor league game was held
