He's got a worse K/9 than Arroyo. He's got the highest WHIP of the 4 guys with 30 starts, just a smidge higher than Latos, but Latos can actually strike guys out. His season is screaming luck, and I'm glad he's getting lucky. But luck doesn't last forever.
The Reds are having a good season. Leake is having a very lucky season.
