What8217s Going on at Safeco Field-

Its not a secret that the Mariners home park is among the more pitcher friendly ballparks within the Majors. Because of its asymmetrical dimensions, its especially good for left-handed pitchers who can take advantage of the large area in left-center field, allowing right-handed batters to Antwan Goodley Jersey drag the ball without getting penalized by as many home runs as theyd allow inside a neutral ballpark. Jason Vargas is the best current example of this phenomenon, as hes allowed just five home runs both at home and 16 on the road this year. However, what's happening in Safeco this year looks like it is going beyond only the park effects that we already know about. For some reason, Safeco Field is simply destroying offense this year in a way that it never has before. Any time we talk about overall run scoring in a specific ballpark, we must take into account the house team that produces an enormous most of the at-bats for the reason that park. And, obviously, the Mariners aren't an especially good offensive team, his or her .293 wOBA ranks 28th in baseball, ahead of only Pittsburgh and North park. Even by wRC+, which accounts for Safecos historical effect on run prevention, theyre still 28th in the Majors in offense. So, naturally, the home of an undesirable hitting line-up may have lower scoring games than average. However, the Mariners arent just equally substandard offensively both at home and on the highway. In your own home, theyre the worst offensive club in baseball, as well as on the road, theyre actually okay. In Seattle, the team is hitting .201/.280/.297, great for a .260 wOBA this season. The next worst hitting team in your own home may be the As, but they are available in at a .295 wOBA. The gap between the Mariners and subsequently worst hitting team at home is really as large because the gap between your As and also the White Sox. On the street, the Mariners are hitting .259/.310/.420, great for a .317 wOBA that really ranks 6th within the American League. When theyve played away from Safeco, their offense continues to be slightly excellent. When theyve played in your own home, theyve been the worst offense within the good reputation for the sport. These results have resulted in speculation about the park stepping into the players heads and questions about if the mental toll of watching balls die around the warning track has started to consider an effect on the teams psyche. Maybe it's, I dont know. But what I can say for certain is this fact isnt an effect that is unique to the Mariners this season. For all the coverage their offensive home/road splits have gotten, the fact that opponents are demonstrating nearly exactly the same effect has gone a bit individually distinct. Here are how other teams have done from the Mariners pitching at Safeco so when they is on the road.Home: .218/.284/.328, .272 wOBARoad: .265/.333/.466, .333 wOBAThe pitching staffs 61 point difference between home and road wOBA is really larger than the batters split. Away from Safeco, the Mariners would be Frank Clark Jersey the third easiest pitching staff in the American League hitting against at home, those are the hardest. If opposing batters are seeing a similar reduction in offensive performance against Mariner pitching in Seattle, this suggests that probably the effect isnt so much a mental i sue with the Seattle hitters and much more of the blanket effect that's suppre sing hitters all teams, regardle s of what uniform theyre wearing. So, why is Safeco holding down runs to this kind of extreme degree this year, for both the Mariners as well as their opponents? Lets break down the constituents for the Mariners offense and their opponents offense by home/road differential. Mariners batters in your own home: 9.7% BB%, 22.4% K%, .096 ISO, .249 BABIPMariners batters on road: 6.9% BB%, 19.7% K%, .160 Larry Warford Jersey ISO, .299 BABIPMariners opponents at home: 7.5% BB%, 21.0% K%, .120 ISO, .261 BABIPMariners opponents on road: 8.0% BB%, 19.1% K%, .201 ISO, .297 BABIPTheres a gap in strikeout rate for both the Mariners and their opponents, so its entirely po sible that theres something going on using the batters eye or even the shadows which has managed to get harder to pick the ball future out of the pitchers hand, but if which was the case, youd probably anticipate seeing a corresponding transfer of walk rate too. Thats not the case, as the Mariners are drawing many more walks in your own home than you are on the road, and their opponents are showing a minimal alternation in the other direction. While its worth noting that strikeout minute rates are up for everyone at Safeco, the driving element in the lack of offense at Safeco is the way the park has crushed hits and especially extra base hits this year. Again, breaking down the components by home/road, but only this time looking at extra base hits per contacted ball. Mariners batters in your own home: 5.3% doubles, 0.4% triples, 2.2% home runsMariners batters on road: 6.5% doubles, 0.6% triples, 4.1% home runsMariners opponents at home: 4.0% doubles, 0.4% triples, 2.9% home runsMariners opponents on road: 7.0% doubles, 0.6% triples, 5.5% home runsDoubles and triples are down, but its homer rate thats really getting destroyed in Seattle in the seasons first three months. The Mariners hit home runs in an 86% higher clip-on the street compared to what they do in Safeco, while opponents are at 89%. In short, Safeco is cutting home run rates for all players nearly in half when compared with what theyre posting from Safeco. This isnt a park effect thats turning home incurs doubles either, as the huge BABIP gap shows that a lot of these balls that might be home runs are in fact getting run-down for outs. From an observational standpoint, it seems that balls are hanging up long enough for outfielders to get under them, so while the dimensions serve to keep the ball in play, its been the marine air that has turned those balls into outs. And, some cursory glances at the weather patterns within the northwest appear to support that idea. The National Climatic Data Center produces maps that show relative temperature index numbers by state, and while June wont be acce sible for a few more days, B.J. McBryde Jersey we can already look at the way the Northwests weather continues to be diverse from the rest of the countries in April and could.For the nation, the NCDC reports April average was 3.6 degrees warmer than usual, with only California, Washington, and also the upper midwest reporting declines from the hottest March on record. May brought significantly warmer temperatures to the rust belt and to California, however, while it actually got relatively colder within the Northwest Washington and Oregon were the only two states to post substandard temperatures in May. Looking at the AccuWeather recorded temperatures for June show that Seattle was still relatively cold, especially compared to the rest of the country. While the east coast is being bathed in 100 degree temperatures this weekend, our prime in Seattle yesterday was 72. For the first few weeks of the month, our prime sat in the mid-50s to low-60s. The Marine air serves to help keep Seattle fairly temperate even just in a normal year, but 2012 has shown to become abnormally cool in Seattle, especially in accordance with all of those other U.S.We realize that there's some relationship between temperature and offensive environment in baseball, though its not a one-for-one tradeoff between heat and runs scored. Humidity is also a factor, and we cant simply state that Safeco is playing as an extreme pitchers park due to the elements patterns within the northwest this year. However, because this article notes, Seattles climate offers two e sentially two kinds of days in the summertime cool and humid or hot and dry. Humidity is highest in Seattle when its cooler, Mike Martin Jersey but because it warms up, the temperature gets farther from the dew point. The recipe for any baseball to fly a long ways is hot and humid air, but that just doesnt appear in Seattle. Its either (kinda) hot or humid, but rarely both. We have pretty strong observational data that shows that Safeco is suppre sing offense far more than it normally does this year, and its probably not a coincidence that Seattle is among the few cities within the U.S. that hasnt really gotten around to using summer yet. When Felix Hernandez was wiping out the Red Sox last night, which was probably more good pitching than favorable conditions. However, it cant be prevented that both Erasmo Ramirez and Jason Vargas tallied up 10 strikeout games earlier in the week, which excellent pitching performances in Seattle happen to be the norm as opposed to the exception even though Seattles pitching staff after Felix is a rag-tag bunch of pitchers. Their starting rotation, in particular, is not very good from #2-#5, but opposing batters just cant put runs on the board in Seattle either. The Mariners dont have a very good offense, however they dont have a good pitching staff, and yet, no one is scoring runs in Seattle this year. Whether its the weather, the batting eye, or something else that people havent considered, theres something going on in Seattle that is making Safeco Field look like a more extreme version of Petco Park.
