Obviously too early to say anything bad, but that is exactly what he looked like last year. This time it took him 5 pitches to strikeout, so this would be one of the highlights of his career in the majors so far. Most of the time it only took 3 pitches.
I know everyone has been waiting for him to "solve" CF, but frankly I would much rather have Herrera and let Moniak hit in AAA for more than a few weeks.
