How to Improve at Home

With the final road trip in the books (as it were), the Mets 2013 road record finishes at 41-40. This is significantly better than their home record, which stands at 32-45 with 4 games to play.

One obvious reason for this disparity would be park factor. While the Mets decided to shrink the dimensions of Citi Field prior to the 2012 season, it’s still not a band box. In fact, you can fit almost the entire field at Citizen’s Bank Park inside the fences of Citi Field:

You can do the same with Great American Ballpark:

Looking at ballpark factors, Citi Field is near the bottom of the league in runs scored (27th).

However, it’s also been the 9th friendliest ballpark for home runs based on a home-to-road ratio 1.139. The problem is, the Mets haven’t been the ones hitting them. A total of 144 home runs have been hit at Citi. The Mets have hit 58 of them. They’ve hit 71 on the road.

According to ESPN’s home run tracker, the Mets have hit a lot of “just enough” home runs at home – homers that barely clear the wall. And just looking at this past road trip, the Mets benefitted by the short dimensions of Citizen’s Bank Park.

At Citi Field, Daniel Murphy and Lucas Duda have 4 “no doubt homers,” Ike Davis has 3, and David Wright has 2. Davis and Duda have the power to clear citi field fences, but are not consistent enough. Wright is consistent in every category, including homers (He’s usually in the neighborhood of a .300/.400/.500 slash line with 40 doubles and 25 homers), but doesn’t have the raw power of a Giancarlo Stanton or even a Davis or Duda.

Putting it into numbers, here’s a look at some batted ball stats at home and away (BABIP = Batting Average on Balls in Play, GB/FB = Ground ball to Fly Ball ratio, LD% = Line Drive percentage, GB% = Ground Ball percentage, FB% = Fly Ball percentage,  IFFB% = Infield Fly Ball percentage, HR/FB = percentage of fly balls that were home runs):

The Mets are second in MLB in FB% at home. With the big Citi outfield, a lot of those are going for outs. As you can see, visiting players have turned a higher percentage of their fly balls into home runs (11.2 percent vs. the Mets’ 7.9 percent).

This is a big reason why the Mets won more games this year on the road than they did at home. It’s the second time since Citi opened that their home record has been worse than their road record.

That’s not to say they can’t win at home – they had winning records there in 2009 and 2010, even before the dimensions were changed. That tells us there are more variables that factor in to home/road W-L records than just home runs, including coincidence. But a team can improve their odds.

Obviously, changing Citi Field’s dimensions again not the answer. Other teams have proven they can hit home runs in Queens.

All of the above research is really just a long way of reaching an obvious conclusion: The Mets need more power. Whether it’s in the form of free-agent 20-homer guys like Shin-Soo Choo or Hunter Pence, or through a trade, they will greatly enhance their chances of winning at home (and elsewhere) if they can add more pop. Whether they can or will make significant offensive upgrades this season is unknown, and depends on many factors.

Pitching and defense are of paramount importance – they are the keys to sustained success. Adding a couple of power bats onto that foundation usually adds up to a winning formula.

    Rubin, in his chat today, has qualitative rather than quantitative reasons for the home/road split. He speculates that it might be because the team is asked to do so many extracurricular things when they’re at home, presumably (my presumption, not Rubin’s) to get a couple more butts into seats.

      To clarify, it wasn’t Rubin’s speculation, just something he heard. I find it hard to believe well-conditioned athletes would be physically worn down by extra-curricular appearances. Of course, it could just be a statistical blip that they happened to play some of their worst ball during home stands, and next year will be different. But I also hope many of the players will be different, and that a couple of them can clear the Citi Field walls.

    Casey Stengel always felt that when players were home they had too many distractions. That explanation doesn’t cut it when your team has a good home record, but it can be a useful crutch when you lose too much at home. Of course, Casey’s Yankees didn’t lose too much anywhere.

    The park size and park factors cut both ways, and in the case of Citifield it aids the fly ball pitcher at the expense of the fly ball hitter. As mentioned, there are many reasons for why the Mets’ home record has been bad for several years. The ballpark is not to blame. They need better players, and players that fit better in their ballpark. Specifically, better defense, more speed and athleticism play better in a “bigger” ballpark. And, since every team needs some power, they need to find a power bat that transcends the dimensions, meaning a guy that can hit HRs and hit a bunch of no-doubters. Ike and Duda fit that profile, but they just aren’t consistent enough to be relied upon for a primary role going forward. For a guy like Tulo, or Stanton, Citifield is not too big.

    It’s because the fans are hating on the Mets.
