The issue isn't the slash line, it's the contact. When Rizzo had his bad callup in San Diego, he whiffed on 31% of his swings, which is toward the bottom of what is acceptable for a MLB power hitter. Baez last year in the majors whiffed on 40.8% of his swings. That would make most pitchers blush. And it's a continuation of a problem we already knew he had. It's really hard to find guys who went on to successful MLB careers with K-rates as high as Baez's in the minors. Even guys like Reynolds and Dunn made more contact in the minors. But all that said, the *good* news is that he's insanely young. I really don't think more AAA would set back his development at all.
