Machemehl put in four years of Minor League ball before making it to the Majors at the start of the season, making his debut on April 6th of 1971.
Over his 14 games, which took place between April and May, he was hit hard, going 0-2 with an earned run average of 6.38 in 18.1 innings of work.
In those 18-plus innings he gave up 16 hits, 15 walks, while striking out nine, leading to 16 runs of which 13 were earned.
He’d be back in the Minors for the rest of the year before playing out his Pro career in 1972 with a split season between the Texas Rangers and Kansas City Royals systems.
Nevertheless, he made the “Big Show” for that one month in 1971, and kudos for that!
