Today we get into the park factors for the full-season teams. In rookie ball, the seasons are short and give you plenty of sample size issues. In the full-season leagues you get 70 home games and 70 road games, and smaller rosters. While there’s still a chance of some sample issues, the larger number of games and fewer number of players help eliminate some of those issues.

Dayton plays in a neutral league when it comes to hitting and pitching. Their ballpark doesn’t stand out in any strange way for it’s dimensions. Historically, though, Fifth Third Field has played out as a little hitter friendly by comparison to the rest of the league.

Before we dive into the numbers below, this is your reminder that they are only being compared to the other parks in the league and not to all parks in the Minor Leagues.

How did Fifth Third Field play in the 2018 season?

The first thing we want to look at is how average was changed by the home ballpark versus the road.

dAVG %Change
To LF -.004 -0.6%
To CF -.005 -0.9%
To RF .065 13.4%

To left field and to center field the ballpark played out about as neutral as it can. There was a difference of less than 1%. But, when the ball was hit to right field in Dayton the hitters saw plenty of benefit in their average, boosting things by 13%. This was a little different from the previous season, but only in right field. It helped in right field in 2017, too, but not quite as much.

But, it’s the power, not the average, that tends to give a ballpark the reputation as being hitter or pitcher friendly. Let’s take a look at how Dayton played out with power, looking at isolated power (SLG-AVG).

The reputation as a hitter friendly ballpark held up for Fifth Third Field once again in 2018. It boosted power to all parts of the field. With that said, it didn’t boost it as much as it had in the 2017 season. Still, hitters certainly got a little more power in Dayton than they did around the rest of the league as a whole.

What do we know from this data?

Well, the park certainly boosts power. We figured that coming in and it held up. With that said, it’s interesting to look into the raw data. There were 10 more home runs hit in Dayton than in road games between the teams involved. Fifth Third Field also yielded a small advantage in doubles (16 more) and triples (6 more). It didn’t really have a big advantage in any one aspect of power, but it was a small boost everywhere that added up. Hitters were the beneficiaries, while the pitchers took a few extra lumps that they otherwise may not have.
