No, that made the All-Star no longer just a fun-filled exhibition game.
Are you aware of the extraordinary thing that happened in the 1954 All-Star game?
[Likely not, so here it is:
Dean Stone was the winning pitcher without throwing a single pitch. He was brought in the top of 8th inning with two runners on base and two outs. Before throwing any pitches, he picked off a base-runner, thus being credited with 1/3 innings pitched and ending the inning. He was removed for a pinch hitter in the bottom of the 8th, as the AL scored 3 runs to take an 11-9 lead. That made him the pitcher of record and 11-9 was the final score.]
