"Mark McGwire, Busch Stadium, May 16, 1998"
In 1998, Mark McGwire set the single season record for home runs with 70. Among those 70 were many very long homers, with his home run off Livan Hernandez at Busch Stadium being known as the longest of the bunch, credited at the time as having traveled 545 feet. McGwire's drive hit the St. Louis Post-Dispatch sign that hangs from the second deck in deep center field; in fact, the Cardinals applied a jumbo-sized "Band-Aid" to the sign thereafter to commemorate the feat. While McGwire's shot was unquestionably a remarkable blast, Hit Tracker analysis suggests that the true distance of this home run feel quite a bit short of 545... First, the atmospheric conditions: 77 degrees, with essentially no wind, at 460 feet altitude. Next, the observation: the Post-Dispatch sign is approximately 441 horizontal feet from home plate, at a height of approximately 46 feet above field level. Existing video of the homer does not record the impact (because the cameraman was not aiming high enough!), but based on the appearance of the ball dropping after impact, the time of flight can be estimated as approximately 5.1 seconds. With these parameters, Hit Tracker yields a true distance of 487 feet, with a speed off the bat of approximately 115 mph at an angle of 24 degrees.
