What record do these two teams share?

[GiambiJuice]

1915 Philadelphia A's
2006 Washington Nationals

And what separate record is held by the 2002 San Diego Padres?

No takers, huh.

Oh well, here's the answer:

The 2006 Nationals and 1915 A's hold the record for the most different players to get an at bat(53)

The 2002 Padres hold the record for the most different players to throw a pitch (37)

Interestingly, 3 of the four top spots on the pitching list are held by SD Padres teams.
