Dukes, who was taken 8th overall in the 1967 January draft by Washington, appeared in five games during the 1970 season, not factoring in a decision while posting a .270 earned run average over 6.2 innings pitched.
The previous year he finished 0-2 in his first taste of the big leagues, while ending up with a nice 2.45 E.R.A. in eight appearances, all out of the pen.
After spending the 1971 season in the Minor Leagues, he’d make it back to the Majors in 1972, now with the organization shifted to Texas as the Rangers.
In his final stint as a Major League player, he appeared in three games, allowing one earned run in 2.1 innings without a decision.
All told, he finished his MLB career with an 0-2 record along with a nice 2.70 E.R.A., all in relief over 16 games and 20 innings pitched.
