hi...no slider tips per se, since I'm using what I posted, but regarding pitching tips:
a) TRY to get ahead of the batter...starting with strike one
b) MIX your pitches. If you don't, it's usually a short matter of time before the CPU will make you pay.
c) INTENIONALLY throw off the plate---especially with 2 strikes. Most batters will chase IF you set them up properly. They may foul off a few, or you may miss with a few, but if your dequence is good, you'll get em...
d) never throw you entire sequence to a batter in the same general area.

As in real life, change his eye level. I think it was Franceour the other night that I'll use an example. Real life history (and The Show '08 history) tells me NEVER throw him a first pitch fastball, unless it's WAY off the plate. So I threw him a circle change for a strike. Then a curve that broke on the outside corner for strike two. Two pitches and he did NOT swing. Then a 4-seam fastball high in the strike zone and in a little...he was jammed and swung anyway---STRIKE THREE!
I'd say on average, I get between 7-9 K's per game
