Mike DiGiovanna writes in today's L.A. Times:

In the bouncing ball of home-plate humanity that punctuated the first walkoff homer of Kennedy's career, the Angels celebrated not only a dramatic victory that extended their win streak to four but a game that may have applied a pair of shock paddles to their pennant hopes.

Fans in attendance at the game played on August 29, 2004 between the Angels and Twins will be surprised to learn that they didn't witness Adam Kenddedy's first walk off home run that day.  

Update - just got an email from DiGiovanna in response the one I sent this morning pointing out the inaccuracy. He noted it and said they were running a correction tomorrow. Problem solved.
