Kenneth Lowther Ash (September 26, 1901 – November 15, 1979) was a Major League Baseball pitcher.

On July 27, 1930, Ash earned a win against the Chicago Cubs with just one inning of relief and with him only throwing one pitch.

Ash was called in to relief by Cincinnati Manager Dan Howley with the Reds trailing 3–2 in the top of sixth.

Grimm tried returning to first, but Sukeforth threw the ball to Reds first baseman Joe Stripp.

Ken Ash was pinch hit for in the bottom of the sixth and Cincinnati scored four runs to take the lead which they held.
