A divisional title is not likely.
The Cards and Astros are more talented than us.
However, we have a team that can win a game or two. We play all the right teams the rest of the way, we need to play our competitors(Astros and Cards) and avoiding the other good teams in the NL and playing the weak ones(No games against ATL, LA, SF, 3 against ARI). I have no clue on the Astros or Cardinals schedule left. But I think it is possible to do, not likely but possible.
