Left winger Mike Corrigan played his Junior A hockey with the Toronto Marlboros, scoring 25 goals and 61 points in 41 games in 1965-66. From there, he toiled in the minors with the Tulsa Oilers of the CPHL and the Rochester Americans of the AHL. The big break for Corrigan, and many others, came in 1967 when the NHL announced it was expanding by six teams.
In 1967-68, Corrigan joined the Los Angeles Kings for five games while playing the bulk of the season in the AHL with the Springfield Kings. He had a very productive season, scoring 24 goals and 54 points in 58 games but he failed to earn a roster spot with Los Angeles the next season. However, Corrigan was inserted into the Kings lineup for 36 games in 1969-70 where he scored ten points.
The Vancouver Canucks acquired Corrigan's services for 1970-71, and in 76 games he notched 21 goals and 49 assists. Midway through the next season, he was sent back to Los Angeles for his second go-round with the Kings where he played a regular role for the club. Corrigan's best individual season came in 1972-73 when he scored 37 goals and 67 points with 146 minutes in penalties, all of which were NHL career highs.
In 1976-77, he joined the Pittsburgh Penguins, where he stayed for a two years before suffering a severely broken leg in a game against Buffalo, 25 games into the 1977-78 season.
