Morrison appeared in five games for the Philadelphia Phillies in that 1977 call-up, batting a robust .429 with three hits in seven at-bats with three runs scored.
He would go on to put together a very respectable career, mainly with the Chicago White Sox and Pittsburgh Pirates, for whom he played ten seasons combined.
Over his career he only had the chance at a full season twice, and he put in very good years both times:
In 1980 he appeared in all 162 games for the White Sox and hit ..283 with 171 hits, 40 doubles and 15 home runs, along with 57 runs batted in and 66 runs scored.
Then years later in 1986, now with the Pirates, he played in 154 games and went on to post career highs with 23 home runs and 88 runs batted in, while also batting .274 with 35 doubles.
Those are some really good numbers for a guy that was really a platoon player most of his career.
By the time he retired after the 1988 season, he finished with a .260 batting average, with 876 hits and 112 homers, with 371 runs scored and 435 RBIs in 1089 games.
