For example, if we go 4-4, we clinch home field. If we go 3-5, we end up tied if the Astros win out. Considering we
play the final 6 at home against the Rockies, I'd say that 3-5 is highly unlikely. We have at least two more Kershaw and Urias starts. Odds are pretty good that we surpass 110 wins.
Also, the Astros play the Rays and Phillies to finish the season. The likelihood that they win all of them is low.
