Cuz Howry (unless im mistaken on who's in, justin miller, bob howry, pat misch, everyone looks the same) fed Griffey 4 fastballs, who's swing is sick no matter how old he is, in his wheelhouse, the last one being a gimme. He got away with an out, Go giants, but a walk-off grand slam by Griffey is something i cant hate on
edit: thats not to say Howry couldnt beat griffey on the fastballs, he worked a good count, but that last one is a lefty gimme
