Thompson was the Cubs' first pick in the June 1974 draft and batted .417 in his 19-game
1978 Chicago debut. He proved a consistent but punchless lefthanded hitter, batting
.289 with just 29 RBI as a rookie in 1979. On July 5, 1980 he was knocked unconscious
when he collided with Pirate shortstop Tim Foli
, and he finished the season at .212.
The Cubs released him in 1983. He led the NL with 62 pinch at-bats for San Francisco
and Montreal in 1985.
