Coming over from the Houston Astros, Larson threw one single inning for the Philadelphia Phillies in 1978, striking out two while giving up one hit, a home run, for a cool 9.00 earned run average.
1979 would pretty much be more of the same, as he’d only get into three games this time, going 1-1 with an ERA at 4.26 over 19 innings of work.
His career would last through the 1982 season when he played his final 12 games for the Chicago Cubs, going 0-4 with a 5.67 ERA before calling it a career.
Overall, Larson threw to a record of 10-25 over 78 appearances, throwing 323.1 innings with an earned run average at 4.40.
Of his 78 games, 43 were starts, most in his first two seasons with the Astros, pitching six of his seven career complete games.
