I kind of don't blame aces for hating the "opener". Takes away any possibility for a shutout/no-hitter/perfect game.
Kinda can't wait for the first time an opener is used, and then the 2nd guy comes in and fires off 8 innings of no-hit ball. Can see a lot of controversy with that.
I wouldn't say he's a little bitch at all, it's totally understandable. These are professionals the would live for a moment like that. To throw a perfect game would be a dream of theirs. With this you're taking that dream away from them.
