To add to yesterday's response. When your top play is an under and it is 1-1 going into the 10th inning and they score 7 runs in the 10th to go over -- then it just is not your night. Then you have Baltimore that cannot score more than 2 or 3 runs in 3 games in Colorado. Then the one game they do score 5 runs they have to do it in the 10th inning. Then they give up 3 in the bottom of the 10th to lose the game as well to one of the worst teams while they are fighting for a playoff spot.
These are simply the things that happen in MLB over a long season. The value is on unders a lot and the extra innings fake runners can kill that. This coupled with the way so many pitchers are used now that 'force' a manger to gamble on the next pitcher he uses being able to continue to shut down a team that the previous 1, 2, or 3 pitchers have shut down. The deeper you get into the weaker pitchers the more likely MLB starters will be able to hit them.
Then you have the 'September Effect' coming with all of those variables coupled with 'tax season' when the favorites will be charged extra juice.
This is not complaints. It is just to point out the reasons that there can be wild swings in MLB. It is already the hardest sport for the better team to win in. For example, in MLB the outcome of a game is the most random of any other sport. It is much closer to a coin flip than others are. In the NFL the better team will win a tad over 58%, NBA, 58%, soccer a bit over 57%, NHL a bit over 55%. In MLB the better team will win only 53.5% of the time. So, you are already having to pick edges where a coin flip is almost as good.
If you strip the luck out of each sport and compare the teams in each sport to see how far apart the teams are you will see on a bell curve almost all teams in MLB are between 38% - 62%. NFL for comparison is 21% - 79%. So, MLB teams are stacked well on top of each other. NFL teams are spread across the entire field.
Reasons for this are not just how much better the teams are themselves. But how much the games themselves bounce around.
In MLB, the better team is 0.7 runs better. Even in soccer a much lower scoring game the better team is 0.73 goals better. In the NFL the better team is 5.79 points better.
The swings, or bounces, in an MLB is about 4.35 runs. This is variance on just luck or bad hops, a windy night, a locked in guy, etc. Soccer will bounce by only 1.82 goals. NFL will swing by only 14.72 points.
So, it may be the same weight on a coin, but MLB shakes the entire table by about 2.5 times harder.
A major reason is that the best players have a much smaller effect on the outcomes of a game than in other sports.
