Last time in this space, I took a look at home runs averages throughout Major League ballparks. This time, instead of comparing ballparks to one another, without adjusting for teams, I'll compare teams to one another, with an eye toward the ballparks. Here are the league averages for a team's home runs on the road and at home. The columns contain the same information as last week, but again, the second column shows how many home runs were hit from 2006-2008 and to what field, the next several columns are Hit Tracker terms, while the last column, parks, shows how many parks each home run would have exited, also a Hit Tracker term.

The only discernible difference that I notice is that there are about two more home runs hit at home per year by a team than on the road. Other than that, the characteristics of home runs at home and away are virtually identical.

On to the individual teams. To view any ballpark's dimensions, go here. I'm going to be looking for characteristics of home/road splits that might signify ballpark characteristics conducive to certain types of hitters, be it handedness, fly ball height, home run distance, or anything else of note.

Arizona Diamondbacks

Chase field is a decent home run park, but the Diamondbacks aren't much of a home run hitting team. Center to left-center field at Chase is extremely deep, but the D-Backs have had some power to spare to left field. However, Chase is neutral to left. I'll keep an eye on their power hitting right handers Chris Young, Justin Upton, and Mark Reynolds

Atlanta Braves

While Turner Field is an average home run park, the Braves have struggled at home. They take advantage of their friendly center-field fence, and as Chipper Jones is one of the best power hitters of all time to center field, I'll keep an eye out on him. As for who might struggle on the road, I'm not so sure. Right field might be a bit challenging in Turner, and the Braves excel going to right on the road, so perhaps Brian McCann or Kelly Johnson are hurt by Turner.

Baltimore Orioles

That's an enormous difference between home and away home runs for the Orioles. A short left field allows for cheap home runs to left, and I suspect Kevin Millar has used this to his advantage. Furthermore, some Oriole hitters might not have had the power to go yard in parks other than Camden. I'd also like to check on Nick Markakis because he isn't paid enough attention.

Boston Red Sox

The Sox enjoy the Green Monster, but they've hit more home runs to left on the road than they have at home. And besides left field and the Pesky Pole, Fenway is an awful home run park. The Sox have had strong center-field power hitters go to waste in Fenway. That's mainly Manny Ramirez territory, so I'll check on him. Dustin Pedroia, Mike Lowell, and Kevin Youkilis likely exploit the left-field fence. Meanwhile, right field is also quite deep, so while David Ortiz has thrived going the other way, pull lefties such as J.D. Drew might be adversely affected. I think it's safe to say that Fenway is one of the more interesting parks in the league, and the extent to which the park helps or hurts players is greater than most.

Chicago Cubs

Cub home runs get a lot of help at Wrigley on fly balls to left from the wind. I'd imagine players who hit the ball high enough to have the ball caught in that wind would be interesting case studies. Perhaps Alfonso Soriano, Derrek Lee, Aramis Ramirez, and Geovany Soto.

Cincinatti Reds

The Reds have hit an above average amount of home runs to all three fields at home, but were average to left and center on the road. Maybe Brandon Phillips is better at home. With Ken Griffey Jr. and Adam Dunn, the Reds have had great power to right field, and it looks like Great American might have aided their totals a bit. Adam Dunn and other players with obscene raw power will be interesting, as I'm not sure whether they're better suited for parks where home runs are common or rare. On the one hand, Dunn is one of the few players who would hit 30 home runs anywhere he played, which would be especially valuable in PETCO, but on the other hand he'd have his home run totals inflated in a hitter's park. But would his home run totals be increased proportionately with someone who hits a lot of wall-scrapers? Or would his long home runs become devalued?

Cleveland Indians

The Indians seem to prefer hitting to right and center field at home. I'll take a look at Grady Sizemore and Travis Hafner.

Colorado Rockies

Ah, Coors Field. Since the outfield area is so great, Rockies hitters don't gain much of an advantage hitting to the deepest part of the ballpark. There's also the Coors Field hangover effect. In general, Rockie hitters are prone to extreme splits, so I'll look at most any of them who played a couple years there, from Todd Helton to Matt Holliday to Garrett Atkins to Brad Hawpe

Chicago White Sox

Well Coors seems tame compared to the Cell. The White Sox hit over 30 homers a year more at home than on the road. This effect is almost entirely directed to left field. It's entirely possible that Hit Tracker doesn't entirely capture the jet stream effect that is felt on the field level, but not detected by flag and wind recordings. Any right-handed hitter is up for a closer look, including Carlos Quentin, Paul Konerko, Alexei Ramirez, Joe Crede, Jermaine Dye and Jim Thome might have his opposite-field home run totals inflated by U.S. Cellular's left field.

Detroit Tigers

If the Tigers have any hitters with center-field power, we wouldn't know, since Comerica zaps all home runs and turns them into triples. That might mean Magglio Ordonez or Curtis Granderson have lost home runs.

Florida Marlins

The Marlins have hit a whole lot of homers the last three years, and they prefer doing so on the road. The greatest difference is in center field. The entire Marlins infield from last year had power that could go on forever, but perhaps the deep center field hindered some of their output.

Houston Astros

The Astros loved going to center field on the road and to left field at home. The distance of home runs hit to left by the Astros is notably short, so that field might not only help the boppers like Carlos Lee and Lance Berkman, but also Hunter Pence and Craig Biggio.

Kansas City Royals

The Royals have had anemic power production, and their home park hasn't helped. I don't expect many informative results to come from looking at Kauffman Stadium. Jose Guillen could be interesting, since he's such a line drive htiter, and perhaps compare him to John Buck who is more of a fly ball hitter.

Los Angeles Angels of Anaheim

The Angels don't hit many out to right at Angels Stadium. My guess is Vladimir Guerrero hits more opposite field home runs on the road than at home. Garret Anderson also seems like someone who would hit some home runs to right just long enough to exit a few parks but maybe not Angels Stadium.

Los Angeles Dodgers

Dodger Stadium is beneficial to power hitters who can hit to straightaway center. Jeff Kent, Andre Ethier and Russell Martin are the only notable hitters with power that the Dodgers have had for more than a season since 2006. I'll take a look at them.

Milwaukee Brewers

Left field in Miller park is less inviting than the other two fields, so I'd guess Prince Fielder prefers playing at home more than Ryan Braun does.

Minnesota Twins

The Metrodome has a welcoming center field, but left field and right field are unfriendly to the Twins. In right field, Twins hitters have had to hit the ball on average nine feet higher to get it over the baggy than they have had to on the road. Justin Morneau and Joe Mauer are both unique players, and they might approach the baggy in different ways.

New York Mets

Center field at Shea was where long fly balls went to die, and Citi Field won't help matters for the Mets in that regard. Carlos Beltran, David Wright, and Carlos Delgado represent the spectrum in terms of sample size and they all hit their share of home runs at Shea, so they will hopefully make for interesting analysis.

New York Yankees

The Yankees use the short porch in right to their advantage, but the Bombers struggled to hit it out to center in the old stadium. Johnny Damon, Derek Jeter, Robinson Cano, Hideki Matsui, and Jason Giambi used the favorable right field more than most, and likely benefited, while Alexander Emmanuel Rodriguez and Jorge Posada might have struggled hitting home runs out to death valley.

Oakland Athletics

The A's really enjoy getting away from McAfee whenever possible. The atmospheric swings are dramatic in the hitter's favor on the road. Jack Cust, as a lefty, might resent his home park, while Nick Swisher had his best year's in Oakland, though it could have been in spite of the park.

Philadelphia Phillies

The Phillies play in a nice hitter's park, and I don't see how one wouldn't be helped by the favorable dimensions, but they have a lot of players worth checking out such as Ryan Howard, Jimmy Rollins, Pat Burrell, and Chase Utley.

Pittsburgh Pirates

Pirate hitters might have average power to left field, but it's masked by PNC Park, where they have had to hit home runs an average of 401 feet to that field. Jason Bay was likely affected by this, He might be the only Pirate worth looking at as a right-hander who has presumably been granted a momentous shift in home field advantage.
