There's no real analysis for you today. Just some information for you to do with as you see fit. Certainly there's no intent to jinx anything or anyone with this post!
This first chart here shows the best records, since 2001, in the NL for one team against another team in that division in a particular year. I chose 2001 because that was the first year that division opponents played a drastically lopsided schedule against one another (18 or 19 games in the NL East and West; 15, 16, or 17 games in the NL Central).
| Teams | Year | Wins | Losses | Win % |
| Dodgers over D-Backs | 2004 | 16 | 3 | 0.842 |
| Cardinals over Pirates | 2001 | 14 | 3 | 0.824 |
| Astros over Pirates | 2006 | 13 | 3 | 0.813 |
| Cardinals over Brewers | 2003 | 13 | 3 | 0.813 |
| Dodgers over Rockies | 2006 | 15 | 4 | 0.789 |
| Marlins over Mets | 2004 | 15 | 4 | 0.789 |
| Pirates over Brewers | 2002 | 15 | 4 | 0.789 |
And then take a look at this chart, showing where five different matchups stand this year. The extra columns should be self-explanatory, but if they aren't, they show first how many games those two teams have remaining, and then what the winning percentage would be if the team that has won the most games so far wins out.
| Teams | Wins | Losses | Win % | Games left | Win % if win out |
| Brewers over Pirates | 11 | 1 | 0.917 | 3 | 0.933 |
| Phillies over Braves | 13 | 2 | 0.867 | 3 | 0.889 |
| Marlins over Nationals | 13 | 2 | 0.867 | 3 | 0.889 |
| Astros over Reds | 10 | 2 | 0.833 | 3 | 0.867 |
| D-Backs over Rockies | 12 | 3 | 0.800 | 3 | 0.833 |
Again, this is just information for you to have as you watch the remaining games this week. There's absolutely nothing in here that's jinx-worthy.
