He appeared in one game for the Orioles on August 27, 1887—pitching a complete game, allowing 16 runs on 16 hits in the loss. An arm injury ended his career and he became an inventor, starting off by inventing various shaving devices.

In 1897, he started the R.M. Keating Company that manufactured bicycles, through his Keating Wheel Works subsidiary. Keating had some success for a time with his bicycle business and may even have invented the first motorcycle, though the company apparently folded before any were released.
