1992 – In a rare spending spree, the Astros sign four free agents, pitchers Joe Boever and Rob Murphy along with infielders Ernest Riles and Denny Walling. It’s the end of the line for Walling who spent eleven years previously in Houston, a vital man in two division champions during the eighties. He’s forced out with a knee injury after three at bats. None of the others are in Houston the following season.
