After the 1986 season, the team had difficulty finding success again. Several changes occurred. The "rainbow" uniforms were phased out, the team electing to keep a five-stripe "rainbow" design on the sleeves. Team favorites Nolan Ryan and José Cruz moved on and the team entered a rebuilding phase. Craig Biggio debuted in June 1988, joining new prospects Ken Caminiti and Gerald Young. Biggio would become the everyday catcher by 1990. A trade acquiring Jeff Bagwell in exchange for Larry Andersen would become one of the biggest deals in Astros history. Glenn Davis was traded to Baltimore for Curt Schilling, Pete Harnisch and Steve Finley in 1990.
