Herrera appeared in 47 games for the Expos in their inaugural season of 1969, batting a respectable .286 with 36 hits over 126 at-bats while playing both the infield and outfield.
Turns out it would be the bulk of his Major League playing time, as he would only play in one game during the 1970 season, never to appear in a game again.
The sum total of his four partial seasons as a big league ballplayer was a .264 batting average, with 61 hits spread out over 231 at-bats and 80 games, pretty much evenly split between the Houston Astros and Expos.
