Jose Fernandez has an elbow injury, which might be terrible news for the Marlins and MLB
That would put Fernandez out of commission for about a full year, which would be a huge blow to the Marlins, who are starting to struggle after an early run that saw them atop the NL East.
It's also a huge blow to MLB as a whole, since Fernandez is one of those most talented and exciting pitchers in baseball. In 2013, he won the Rookie of the Year, thanks to a ridiculously incredible campaign in which he went 12-6 with a 2.19 ERA, .979 WHIP, and struck out 187 in 172+ innings.
Fernandez has a chance to be the best pitcher in baseball if he comes back strong, with or without surgery. The key is that he absolutely has to to come back to his former level.
The loss of Fernandez for a year would be devastating. If they lose him for longer than that, the game will suffer.
