My favorite Ortiz postseason story is that in that he actually got two walk off hits in that same series on the same day!!
His home run in game 4 came well past midnight, even out here in the Central Time Zone. And then later that day, he singled in Damon, who was able to “run all the way to New York!”
Two walkoff postseason hits on the same day - that has to be a record.
(If memory serves, the NLCS game that day between Houston and St. Louis also ended in a walkoff hit. 3 LCS walkoffs on the same day is just flat out awesome baseball.)
