ARLINGTON -- Josh Hamilton's June 27 home run against the Astros is now the longest homer hit in the history of Rangers Ballpark. Originally estimated at a distance of 468 feet, the Rangers contacted University of Texas at Arlington professor Andrew Brandt to determine the correct distance. Brandt, a particle physics professor, determined that the actual distance was 490 feet, making it the longest homer ever hit, ahead of Jose Canseco's 1994 blast of 480 feet.
"This is cool, man. I'm glad the Rangers did this," Hamilton said. "I'm excited to hold the longest home run in the park now." Brandt combined various data with a measurement of the time of flight of the homer (about five seconds) with the wind and weather to determine the actual trajectory. He determined that the full flight of the ball all the way to the ground level is how he determined the more accurate distance. "A lot of the other distances of home runs they consider where you hit it to where it reaches the ground," Brandt said. "When you add on that extra distance from the upper deck down to the ground, that gives you an extra 25 or so feet. That's putting you in record kind of territory." But Hamilton insisted it wasn't the farthest homer he'd ever hit. "There was one ball that I know for a fact what it was. In the Minor Leagues, it ended up at 549 feet," he said. "That's just because there was a mud canal behind the field and we found a ball stuck out there. We went out and measured it. There might have been a little error, though, but that was probably the farthest." As the video board displayed the top three home runs in the history of the ballpark, Hamilton coincidentally came in third place with a 460 foot home run. Naturally, he thought Brandt should look into it. "You might need to check some other ones," Hamilton said, laughing. "That 460 one looked a little better don't you think? Maybe make it 475."
