What happened: Plunk went from New York to Oakland in December 1984 as part of the package for Henderson. He returned to New York in June 1989 when Oakland reacquired Henderson.
Why it matters: The transaction symmetry tied one reliever to two separate blockbuster moves involving baseball’s career stolen-base leader. Henderson’s 1989 return helped Oakland win the World Series that October.
By the numbers: The 1984 trade sent five players, including Plunk, to Oakland. The 1989 deal sent Plunk and two others to New York.
