The list includes Bill Bean (career OPS .574), who went 3 for 4 on October 1, 1989. That's the time of year you'd expect to find someone of Bean's ilk batting third in the lineup.
Then there's Orel Hershiser, who officially started at third base on September 15, 1993 so that Dave Hansen could bat for him in the first inning in pursuit of a pinch-hitting record. Pedro Martinez did the same thing five days later.
There's Mike Kinkade, Mark Sweeney, Delwyn Young, Tom Goodwin (!), Antonio Perez. ... Oscar Robles hit third 11 times for Jim Tracy's 2005 Dodgers.
