Re: Your call
Chip's is a good nominee. Let me also add Frank Pulli's blown call on Dave Collins' catch in Game 2 of the 1979 NLCS. Pulli said he trapped it, which he didn't. That allowed a run to score that shouldn't have, and the Pirates ended up winning that game something like 2-1. (Didn't it go extra innings?) With a win in that game, the series is tied 1-1 and the Reds have a shot.
Help stamp out, eliminate, and do away with redundancy.
