Baseball shots tips

Hi,

I've got some good seats to see the Padres take on the Cardinals
tomorrow night, so I'm hoping to take some shots with my new D50. I have
the Nikon 18-70mm (f/3.5-4.5G) lens and also a Sigma 28-300 (f/3.5-6.3),
and was hoping for some tips on settings etc for getting decent action
shots, as well as some wider angle scenes of the ballpark. I'm very new
to DSLRs so I won't be offended at what you may consider the most basic
help! Shutter priority and keep it as fast as the light will allow?
Sports mode? I won't be taking a tripod.

Thanks for any help...
