Ellis Ferguson "Cot" Deal (January 23, 1923 – May 21, 2013) was an American pitcher and coach in Major League Baseball.

After signing with Pittsburgh, he spent 1940 with the Hutchinson, Kansas team of the Western Association, hitting a .312 average while splitting time between the outfield and third base.

In his first major league at bat, he connected a game-winning RBI single off Cleveland Indians pitcher Bob Lemon, while posting a 0–1 mark in five appearances.

His highlights included starting and completing a twenty-inning game for Columbus against the Louisville Colonels on September 3, 1949, and collected four hits in eight at bats.

Between 1951 and 1959, Deal spent most of those years with the Cardinals' AAA International League farm team, the Rochester Red Wings.

Following his playing career Deal served as a pitching coach for the Cincinnati Reds (1959–60), Houston Colt .45s (1962–64), New York Yankees (1965), Kansas City Athletics (1966–67), Cleveland Indians (1970–71) and Detroit Tigers (1973–74).
