Laboy, who was the National League runner up for Rookie of the Year in 1969 in Montreal’s first season, quickly found himself down to a part-timer by his third season of 1971, then ultimately done as a Major league player by 1973 after appearing in only 22 games.
Over those 22 games for the Expos, he batted .121 with four hits over 33 at-bats, with a couple of runs scored and runs batted in.
In 1969, he put in a very nice rookie year, batting .258 with 18 homers and 83 runs batted in, along with 29 doubles after toiling in the Minors for 10 years.
But in 1970, the Sophomore jinx took full charge as he hovered around the Mendoza-line, finishing up at .199 with only five homer and 86 hits.
According to Baseball_Reference, it seems he never played any type of Pro Ball after 1973, just wrapping up his Big League tenure with a career. 233 average on 291 hits in 1247 at-bats in 420 games.
