And here is that home run, off a ball on the lower inside corner of the zone. Juan Francisco's Giant Splash Hit was the longest home run of the season to date, the second-longest HR in GABP history at a reputed 502 feet - and the only to clear the Moon Deck in the stadium's history. The distance was announced over the GABP pubic address system. As Slyde and Big League Stew notes, the 502 ft distance is disputed by ESPN's HR Tracker, which lists it at 482. That would bump it down to 6th longest in GABP history (though that list does not appear to have been updated since '08).
