The only thing about that is the Cubs/Cards and Brewers/Reds play at the same time on Saturday. Unless the other game ends first, the Cubs won't know that they clinched (in that scenario) when the game ends. If we took 2/3 from Milwaukee, our magic number would be 2. If we win Friday and so did Milwaukee, our magic number would be 1. If we won Saturday, it wouldn't matter what Milwaukee did, we'd clinch, right?
