It's not an obsession with K's, but with a 3.66 ERA repeating AA/AAA last year, De Jong really needed strong peripherals to differentiate himself from a ton of other minor league pitchers. For the record, De Jong's K% was below league average last year, at every level he pitched. AA: 17.3%, versus a league mark of 20.9% AAA: 20.2%, versus 22.0% league MLB: 17.6%, versus 22.6% league Now, he may have talent/potential worth claiming, particularly with one option year left, but it's not necessarily evident in his stat lines to date.
