Sano was just promoted to AA after hitting 16HR's in 56 games (1.067 OPS). That's in the FSL and not even Stanton was that good.
Rosario was also promoted to AA with a rather pedestrian .903 OPS in the FSL. Not overwhelming numbers overall but he's still 21 and there were encouraging reports about his defense.
Buxton is likely to be promoted next week from the midwest league (another pitcher's league) with a 1.001 OPS. Here's a video of a triple showing his speed. http://www.youtube.com/watch?v=1OxX4ZX05WY
Alex Meyer has a sore shoulder.
