I was at game on Saturday and Monday and Mitchell was easily the most impressive white sox player over those 2 days, easily. The kid will be called up at the very least as a September call up this year. He is a good sized kid who can fly. He showed his speed on a triple that was to the left field gap. Pretty impressive to see someone leg out a triple to left field. I was surprised how big he is.
I also thought De Aza looked pretty good as a 4th/5th OF. Good skills to have on bench.
