On June 16, 1991, Otis Nixon had 6 stolen bases vs the Montreal Expos.
Tony Gwynn had 5 against the Houston Astros on Sept. 20, 1986.
It looks like Damian Jackson had 5 for the Padres against the Rockies on June 28, 1999
Davey Lopes did it against the Cardinals on August 24, 1974.
There may be more....this is what I found after looking for a little while. Hope it helps.
Well Look who has come to the cafe, It's Mr. Met!
