Last night the 108th home run was hit in Citi Field for the season, matching the total number of home runs hit in the 2011 season. As usual, I have compiled two images: 

The image on the left depicts home runs that only would have gone out of the original fences (Red), the 2010 and later fences (Green) and the 2012 fences (Yellow).

The image on the right shows value of each home run (Grand slams are the largest circles, solo home runs the smallest), and which team hit the home run (red are opponents, blue are Mets).

There have been 178 runs scored via home runs so far in Citi Field on 108 home runs.
Opponents have scored 103 runs on 61 home runs while the Mets have scored 75 runs on 47 home runs.

There have been 29 home runs this season that would not have been home runs using last years wall configuration, from which 51 runs have scored. Of these, opponents have hit 15 home runs scoring 28 runs while the Mets have hit 14 home runs scoring 23 runs.

With the Mets falling off the cliff in the second half thus far, it isn’t surprising to see the opponents hitting so many home runs recently. In the past ten home games the Mets have hit 7 home runs scoring 7 runs while their opponents have hit 16 home runs scoring 27 runs. This is an absolutely massive difference in power production. And it certainly has not helped the Mets win/loss record during this time.

I am surprised by how even the home run numbers are between left and right field. They have been roughly even, if not exactly even, for most of the season. There are swings in either direction, for instance in the past ten home games 12 of the 23 home runs have been to right field. But as you can see, it exactly balanced out the prior bout of hitting more to left field. 

It seems that, at least for this season, Citi Field is balanced for left and right hand hitters. Which is something that I would not have guessed prior to the season. I assumed there would be more home runs to right field. Especially since Jason Bay has not hit for any power in years while Ike Davis and Lucas Duda were both going to have full seasons; both of whom coming off of a hugely productive last month to month and a half of their prior season (Ike Davis of course having his month and half unfortunately cut short due to injury).  

Unfortunately, both players have had sub par seasons characterized by short bursts of production saddled between long droughts rivaled by only the Atacama.  Their massive slumps, along with the unexpected production by Hairston have likely influenced the balance of home runs in a significant way, and it will be interesting to watch how fair the field may turn out to be in the years to come.  I expect a trend towards more home runs going out in right field, especially if Davis and Duda pan out as productive power bats in the future.

It is August 13th, 115 games into the season, and there have been as many home runs in Citi Field as there were for the entirety of last season. Last season the Mets hitters hit 50 home runs while opponents hit 58. So far this season the Mets have hit 47 home runs while opponents have hit 61. There have been roughly 27% more home runs due to moving in the fences (29 home runs that would not have been so last season), and roughly 29% of the games left to play. I fully expect to see just about exactly 30% more home runs this season than last season, giving a total of 140 home runs.

So let me put this in the little red book, 140 home runs at Citi Field this season.

The next major update/compilation will be after game 162, and we will see how close my prediction is to reality. In the mean time I will continue the daily updates for home runs hit in each particular home game.
