Free agent Nolan Ryan signed with the Texas Rangers on December 7, 1988, making him the first major leaguer to play for all four original expansion teams. (The Rangers organization had played their first 11 seasons as the Senators in Washington, D.C.) Ryan first broke into the big leagues with the Mets in 1966, then went to the Angels in a trade in 1972 before signing with the Astros, who were originally known as the Colt .45s.
