 Biographical Information
Dad's best year in the majors was in 1893 when he went 12-9 for a St. Louis Browns team that finished well under .500 at 57-75. Dad was the only pitcher on the team with a winning record. At age 26, he was the same age as fellow pitcher Kid Gleason who went 21-22.
Clarkson finished out his career with the famously-successful 19th Century Baltimore Orioles, who won the pennant both years he was with them. In 1895, he went 12-3 in part of a season (the Orioles had released Kid Gleason before picking up Clarkson), but in 1896, in spite of going 4-2, Dad's ERA was worse than the team average.
His career overlapped with that of his brother and Hall of Famer John Clarkson, but another brother Walter Clarkson didn't pitch in the majors until years after. John and Dad were on the same team with the Boston Beaneaters in [[1892 Beaneaters]|1892]], a team that won the pennant, although Dad pitched in only one game. He won that game, giving up only one run in 7 innings. During his major league career, he was used a total of seven times as a fill-in umpire, all in the National League between 1893 and 1896.
After his major league days he was signed to pitch in Milwaukee by manager Connie Mack. The book Connie Mack and the Early Years of Baseball claims that Dad "never got into playing shape and was inconsistent except in his drinking".
In 1897 the Cambridge team approached Clarkson to play for them, but he turned them down.
