I don't think I have to write too much about this one, because all of us remember it well. Aramis' walkoff completed a 6-5 comeback win over the Brewers, coming back from a 5-0 deficit in the first inning, and was probably the signature moment of the 2007 season.
Here's what I wrote about it at the time.
Courtesy of BCB reader John M, here's a diary that contains three broadcast calls of the HR -- Len Kasper's from TV, Pat & Ron from WGN radio, and Bob Uecker's from WTMJ in Milwaukee.
Those calls ought to warm you up on a snowy day in the Midwest.
