Bass saw six pitches, all of them sliders. Keith Hernandez had told Orosco before Bass's at bat that if he threw Bass a fastball, there'd be a fight. Bass laid off three, but swung and missed three.
I also remember Ashby missing the squeeze with Bass at 3B, which would have made it 4-0 in the first, and who knows...
