The Phillies' farm system was cranking out young outfielders during this time: Johnny Briggs made the team in 1964; Alex Johnson (1965's addition) was shipped off to the Cardinals as part of the deal that brought Bill White and Dick Groat to Philly after the '65 season. Early in the 1966 season, Phillips was traded to the Cubs in the Fergie Jenkins deal. For the next 3 seasons ('66-'68) he was Chicago's regular center fielder.
In June 1969, Phillips was traded to the Expos (with pitcher Jack Lamabe) for infielder Paul Popovich. He immediately assumed the starting centerfield job in Montreal, but after 6 weeks was replaced by journeyman Ty Cline (among others).
In 1970, Adolfo alternated in center field with Boots Day and Jim Fairey, then spent all of 1971 in the minors. After the season, he was sold to the Indians. In 1972 he only played 12 games for Cleveland, while spending most of his final season with triple-A Portland, Oregon.
Phillips' final card was in the 1971 set.
