A Marysville pitcher, Larry Christianson, played for the Phillies back in the '70's.
From an article comparing his team to today's Phillies:

"Unlike the 2008 mashers, who specialize in late-inning lightning, the 1977 team ended a lot of games early. After the Phils sent a pitcher to an early shower one night, a scout cracked, "The least this team could do is wait until the fans got to their seats." And the '77 team could longball an opponent from any spot in the lineup - even No. 9. Carlton batted .268 with three homers and 15 RBI. Larry Christianson also hit three with 13 RBI."

A pitcher that was capable of hitting 3 homers in the series is unusual today.
