Last week we started looking at how each stadium in the Cincinnati Reds farm system plays when it comes to hurting/helping the hitters and pitchers. You can read the entire series here. Today we jump down a level another level and check out things for the Arizona League Reds (you can see the 2015 park factors here).

The Arizona League Reds play their home games at the spring training complex in Goodyear, Arizona. The team is relatively new, dating back to 2010  – before that the Reds played in the Gulf Coast League in Sarasota. The Arizona Rookie League is a bit hitter friendly, though it’s not known for boosting power numbers as much as it is simply for boosting runs scored – or so that’s been the case in the past. That’s not surprising given the relative age of many of the players in the league and how far they tend to be from their full power development.

Before jumping into just how the park played in 2016, we need to be sure to note that the numbers below are only for how things played out in Goodyear versus the rest of the league and not other rookie leagues or minor league stadiums throughout all of the minors. It’s also worth noting that the Arizona League plays the fewest games of all leagues in the minors, so we are working with a very small sample size.

Let’s take a look at how the home park in Goodyear altered the batting average for players.

dAVG %Change
To LF -.031 -5.04%
To CF .015 2.56%
To RF .055 10.17%

Left field played a little bit negative for the second straight year when it comes to batting average. Balls hit to center did get a small boost in performance, but it was right field that saw the most improvement versus road parks in the league. Baseballs hit to right saw a 10% improvement in average versus ones hit to right on the road.

It’s the power output at a stadium that usually gives a place the “hitters/pitchers park” designation. For this we are going to look at Isolated Power, which is average subtracted from slugging percentage – giving us just the extra-base hits portion of slugging.

dIsoP %Change
To LF -.154 -65.53%
To CF -.066 -40.24%
To RF .084 42.64%

The differences here are sort of incredible – but, as noted above the small sample size can come into play here and I believe that is what we are seeing. In games involving the Arizona League Reds this season there were only 33 total home runs hit. With such a small number of total extra-base hits, a few extra home runs simply being a random thing as a whole can alter the overall sample. With that said, there were 13 home runs hit to left field in road games compared to just five in home games. That’s nearly three times as many, but last year the same stadium barely saw much different between home and road power to left. Even more, in 2015 center field dramatically boosted power, while this season it seemed to crush power output. Right field really boosted power this year, and last year it was nearly the exact opposite, hurting power output by 43.6%.

In 2014 center field hurt power output, but the corners both helped. While it’s possible that there was some weather factor playing in, with the small sample size of the season, it’s more likely a combination of just random variance in performance and the players involved in the league at a given time.
