He pitched in 11 games for the Los Angeles Dodgers during the 1973 and 1974 seasons.

Shanahan never did pick up a victory in the major leagues but on the final day of the 1973 season, he did pick up his one and only MLB save.

It came against the Padres and Shanahan pitched 4 very effective innings, allowing only 1 run on 2 hits and nailing down a 3-2 victory.
