After being out of pro baseball for six years, Najo, at age 39, staged a short-lived "comeback" in 1938 with the McAllen, Texas Palms of the Class D Texas Valley League. He played in 137 games, collecting 130 hits, a .354 batting average, and a .976 fielding average. He followed that up with two seasons as a player-manager in the Mexican League, with the Alijadores de Tampico of Tampico in 1939 and the Diablos Rojos del México of Mexico City in 1940.
