Input: Question: Is Class C the highest league in the Texas League? Passage:Dale began playing baseball in the semi-professional Trolley League in St. Louis in 1908. In 1910, he debuted in minor league baseball as a pitcher for the Dallas Giants of the Class C Texas League, which became league co-champions that season. He pitched to a 107 winloss record in 204 innings pitched. Though the Boston Red Sox of the American League gave Dale a tryout before the 1911 season, he did not make their roster, and Dale returned to Dallas. After pitching to a 128 winloss record with 179 strikeouts for Dallas in 1911, the St. Louis Cardinals of the National League (NL) purchased Dale from the Giants towards the end of the season. He made his Major League Baseball debut with the Cardinals on September 19, and pitched to a 02 record with a 6.75 earned run average (ERA) in innings.
