I will give you 3 of mine:
1979 All Star game in Seattle when "The Cobra" Dave Parker had the best throws I ever seen from the outfield in a All Star Game gunned down Brian Downing at the plate to key the NL 7-6 win.
1983 All Star Game in Chicago at old Comiskey Park when Fred Lynn hit the Grand Slam home run off Atlee Hammaker to key the AL 13-3 win
1997 All Star Game in Cleveland when Sandy Alomar Jr the hometown Catcher hit the go ahead homerun to give the AL 3-1 Win.
