But Medina’s performance has been almost exactly replacement level this year.
Here’s another true statement: Medina is great right now. That’s kind of confusing, what with all the bad statistics I just hit you with in the last paragraph, but I was cheating.

He’s running a 2.23 FIP, and he’s doing it by striking out 30% of opposing batters and walking only 5.6%. In other words, he’s an ace — or at least, he was one in July.
