Two pitches after Jason Heyward lined a home run over the right-field fence in the fourth inning Monday, Justin Upton hit one over everything in left field at Champion Stadium. Over the fence, the grass berm, advertisement flags atop the berm, another fence -- everything. “Second-longest home run I’ve seen in a game,” Heyward said of the Upton blast, which hit the top of a tree beyond the berm and cleared a chain-link fence between the backside of the berm and the players’ parking lot. No one could remember a longer homer hit to left field since Champion Stadium opened in 1997, not even in batting practice. The general consensus was it traveled at least 450 feet, which may have been a conservative estimate.
