From hit tracker online dot com this is the founder this website which by the way is now ESPN's home run track. This guy found this web -- in ESPN now he's partnered with him their stats and information. Q tell baseball fans how far these home runs really aren't going. His name is in -- help them but chooses. -- -- -- -- -- -- Greg Vacek you -- Got it all right Greg has said joining us here on the Columbia exterior home improvement hotline so let me just ask the open ended question first. How do you track how -- home run gives. Okay well I'm as you mentioned already I'm one of the tricky things about figuring out how far home run goes is that. Most of the time the home run never actually gets all the way back down the field level. Where you can just kind of take out a measuring tape and figure out how far it landed in fact only about one out of every ten home runs. And at field level also. I'm the trip to measuring a home run into accurately recreate the trajectory. -- -- -- -- And then project that trajectory back down to field level so you can give every home run. A distant guitar on a sort of a level playing field overall. Measured the same way. So I'm contracted the technology behind him tractor then that's very hard and aerodynamic model -- batted baseball. So it's got all the different sources that are in play when the ball was flying through the Hairston got. Gravity that's gonna pull the ball downward as it's flying through the air you have wind resistance or or try force which kind of pushing back in the opposite direction of the ball motions and have a good source. Less well known that's called the madness -- -- fumble forced replies to a spinning ball and where it actually doesn't have a ball that's. Having backs then we will actually carved up to lift up. Can't defend the fact that you see on the news that golf ball that -- kind of do that sort of blew me in shape to the. Trajectories so you -- all through these different forces on the ball. And you have this aerodynamic model he's feeding into an observation though where the ball land and how long it takes to get there so. Obviously. A line drive home run will -- in a certain spot in the seats after a short period of time in the very high American ball. Landed in the seats after a longer period of time. And you take -- imports to the Internet dynamic model and you also include the weather conditions so the temperature in the wind. And and these attractive. Tour will recreate the trajectory of the ball and then -- projected track down the field level don't tell you how far it would've gone had it not been interrupted by whatever. Heard it and you all right so how accurate is that. Well -- actually very accurate. I'm as long as you get a good look at where the ball land and as long as you're able to figure out exactly where that spot is that the ball landed -- impacted. Will be contesting ESPN prior to the adopting. This tournament starting our work together and we did some testing that should miraculous about landed -- -- So it's actually very accurate. And you know again the -- she knows exactly what -- the impact and so if we go out there and talk about that pujols home run for a moment the don't -- shorter. Probably do that deceptive part of our life people's -- that -- -- must've gone a lot farther than that. -- that they're not really. You know understanding exactly what the -- here how far. -- of that second deck where the ball hit. And a lot of times you'll find that any rather -- closer to -- line -- closer to a foul pole. You know there. -- stand -- chance to -- beyond them are actually a lot closer to home plate then that came. Jason would be further out to -- left center field. To do we just naturally kind of overestimate. How far these things go because I was look at on your website and I guess the farthest. All year was Prince Fielder for 86. Yes definitely reflect on that can actually Ruth on the home run found the trouble is that Tom over the course of many years. On Paper you have and exaggerating how far a month ago and not necessarily. Because. They're trying to mislead anybody but it actually rather difficult to. Make an estimate of how far Broncos. On because people often betrayed by the education mound if you had you know math class. Sometime in high school mrs. at one point or another studied. Protect our motion where they teach you that anything that flies in the flow of the parabolic path. Well -- the truth is that. To make it simple enough for a high school student to to do the math they take our existence and that haven't should be -- really important part. Figuring out the aerodynamics of where the ball's gonna land because the wind is pushing back on the ball the entire time it's flying through the air. You tend to start out a home run will look very flat and very fast trajectories so typical home run comes off the bat. Had about a 105. Miles an hour and had an angle about 2728. Degrees. It's like to. By the time it's coming down out in the outfield. It slowed down to probably 55 to sixty miles an hour and it's usually defending at an angle of about fifty degrees. Because the resistance is actually depended. That I'd rather that would existed in a vacuum. And has kind of flattens the entire trajectory back towards home plate so. When you -- the ball rocketing off the bat and maybe hit kind of pumping high up like this pujols home run did. You've seen the movie. The flat and fast part of the trajectory and you know a little bit less. Will be kind of slow and finished that trajectory. And that that kind of contributes to why people. -- you may be overestimated listen to these home run some time. It's funny I'm watching them on the website it's cool you can. You can actually watch the home runs like -- I clicked on the Prince Fielder and I'm watching the replay of that -- it looks like have. Looks like a big home run that I I wouldn't watch that and say that's the longest home run of the year. Yeah you're deceptive he's flew out toward right center field in Houston. Interestingly if you watch the video He landed in somebody's popcorn -- -- a -- a kind of funny. The ending to that home run but because he's got a little bit further towards. Right center field. You know and then because that is a fairly big ballpark in that direction it doesn't look quite so impressive. You know you often feel like I -- -- -- Fenway Park to left field it clean and everything goes up over there. On this particular over the street behind the monster seats. And -- in the parking lot out there and and everybody's really im amazed and impressed by the but factor that's just very. Very close to home plate because that's the way Fenway Park is laid out. -- we hear these stories and Mickey Mantle and Ted Williams hitting 510. Foot bomb does that. How accurate batters that just now at this point legend. Well you know some of those numbers are probably accurate. On little things that it was a big difference about some of oh home runs from a long time ago compared to now. It was a big east Palestinians were very different back -- Fenway Park where Ted Williams hit a home run. I'm commemorated by a red -- in right field. The Red Sox have measured at minus 500 in two weeks. I'm actually I'm right now just -- went even further than that that. Just -- -- you know the horizontal distance too and it landed about thirty feet up in the in the stands in right field. Can hit that -- on a day where there was about a twenty mile an hour wind blowing from behind him out towards right field. And back then the ballparks -- a lot smaller. And then you know maybe the -- -- -- -- that way we approach our ballpark was shorter so they'll win would have a lot more chance to look. That and help to get some of that distance. -- you compare and contrast that to some of the ballpark preceding days. You know third -- tie and then maybe a 150 feet up off of the ground. And drew -- close. You don't get -- windy days. There are gonna have the being blown them. -- to such an extent to the outfield that that's one thing. You know on the other hand you know a guy like Mickey Mantle. You know unquestionably hit in the -- home run derby He was just an extraordinary talent. -- for someone that was not giant like a Mark McGwire on the He was just a very special talent. And you know take another person like they group them in -- who probably never see another player that can hit the ball as far as He could. Okay so last question we talked about Prince Fielder some run this year it went 486 I was the the top home run for. 2011 since you've been doing this what is the longest home run you trapped. One -- -- I have seen in the time I've been attracting home runs for Major League Baseball was hit by Adam Dunn. Back at the very end of the 2008 season for a short time He was on the Diamondbacks. And He had a. Honolulu blue. Line drive to center field that way up on the scoreboard at Chase Field and we protect without the distance at 504. Feet. And that's actually the only home run that I've seen hit in there actual Major League game. But it's clear that 500 foot mark in that time I think we may have seen one or two there were up in the short ninety's as well. But that's wrong it's my team that Adam Dunn had an it's too bad He wasn't able to get down to Chase Field for the home run derby. You would have been nice to see him take another shot at that. While while great info -- website we're talking about here is hit tracker online dot com ESPN uses it baseball Major League Baseball uses his name is. Greg bark chicken he's the founder gets -- Greg thanks for us take some time -- here. Aren't.
