Nottebart actually began the season with the New York Yankees, appearing in four games for them before ending up with the Cubs after being traded from the Cincinnati Reds, who had him returned to them from New York.
In those 20 games overall, Nottebart went 1-1 with an earned run average of 6.38 over 24 innings pitched, both decisions coming with Chicago.
Originally up with the Milwaukee Braves in 1960, his best season in the Major Leagues would have been 1963 when he posted a record of 11-8 with a 3.17 earned run average in 31 appearances, all but four as starts, including the only two shutouts of his career for the Houston Astros.
He would remain a starter the next two years before moving on to the bullpen when he joined the Reds, even posting 11 saves for them in 1966 when he appeared in 59 games and posted a nice 3.07 ERA.
Overall, he finished his MLB career with a record of 36-51, with an ERA of 3.65 in 296 Big League appearances and 928.1 innings pitched, with the aforementioned two shutouts and 21 saves.
