Marlins name Wei-Yin Chen their Opening Day starter under the phony excuse that pitching Jose Fernandez in the second game will help limit his innings, even though the rotation order rarely stays set in stone all year. Pretty clear that the real reason is that Opening Day is a sellout for basically every team. And since the Marlins can't draw for shit the rest of the year they'd rather save their marquee pitcher Fernandez for the next game.
Hope teams don't start making a trend of that. Your best pitcher is supposed to go on Opening Day. It's not that complicated.
