The Longest Home Run David Laurila Has Ever Seen

In the introduction to the most recent edition of FanGraphs Audio — featuring interviews with Tampa Bayers Will Rhymes and Luke Scott — David Laurila notes that the longest home run he’s ever seen was hit by Miguel Cabrera during batting practice before a recent Tigers-Red Sox game at Fenway Park.
Laurila goes on to say that said home run was hit over the Bank of America sign in center field — which sign I have brought to the reader’s attention via red circles by means of a program similar to, but not precisely the same as, Adobe Photoshop.

I know homeruns aren’t typically measured in bp, but does anyone have at least an estimated number on how far it was?
