Yeah, Walker has been tremendous the last 4-5 weeks. And, the first time I saw him take BP last year in Cedar Rapids, you could see just how special his bat and his power were. As some have said, he looks the part of big league right fielder; a big, strong guy with good (not great) speed and a strong arm. I do think that he's improved his plate discipline this year and is walking at a higher rate. As for Rosario, I think he'll be up in September, but I definitely think he could be starting left year in left... He may start the season as the starting CF (until another highly-touted prospect is ready).
