The first half of the season is over, tonight is the Homerun Derby, and here are my two graphics depicting the homeruns hit in Citi Field during the first 86 games. It happens to be a nice round number at the halfway point, 80 homeruns.

Just as when I depicted the First 49 homeruns, the image on the left shows homeruns in my usual format: Red dots are homeruns in all wall configurations, Green dots are homeruns in 2011 and 2012 configurations, and Yellow dots are homeruns on in the 2012 configuration. In addition I have drawn lines separating left, center, and right field (30 degrees drawn from homeplate) and added counters for the number of homeruns have landed in each arc. Finally, I have noted the number of homeruns hit into each wall configuration (Red, Green, and Yellow).

The picture on the right shows the homeruns separated by Mets hitters (blue) and Opponents (Red). The size of each dot represents how many runs it scored. The largest dots are grandslams, the smallest are solo homeruns.

So, a few facts we can draw from this:

- There are 19 homesruns hit this season that would not have gone out of the park given last years dimensions. This is an increase in homeruns of of 31%.
- 12 of these extra 19 homeruns have been hit by the Mets (63%).
- These extra homeruns have scored 37 runs which would not have scored via the homerun given the original park dimensions.
- 24 of these extra 37 runs were scored by the Mets (65%).
- 38 homeruns have been hit by the Mets in Citi Field, 42 by the opposition.
- There have been 137 runs scored via homeruns in Citi Field, 67 by the Mets, 70 by the opposition.

Without the new Mets configuration, the Mets would have been out homered 26 to 35, and they would have been outscored via homeruns 43 to 57. Moving in the fences have clearly helped the Mets more than the opposition up through this point in the season. 32% of the homeruns hit by the Mets this season, which accounts for 36% of their runs scored via homeruns in Citi Field, would not have left the park last season.

***Clarification of the Green dot: If you can imagine where the tall left field wall ends (which was just under 16 feet), the lower section of wall wrapping from this point in left center, around center field, to the Big Apple (where it shot back up to just under 16 feet), and around to the bullpen in right field was all just under 11 feet tall. At least originally. After the 2010 season, this section of wall was reduced to 8 feet in height, which was easiest to see on that section of wall protecting the Big Apple (where it dropped from just under 16 feet to 8 feet).*

*The difference in height from the old 11ish foot wall to the new 8 foot wall is represented by the Green dot in my graphics. When I began doing this, I thought the difference in wall height would be irrelevant, but of course there had to be two homeruns hit against this section of wall during the games, so I was forced to include it. I am sorry if this causes any confusion.***
