Right, but he also only has 45 starts to his name to date....and considerably low number versus lefties. As far as speed and SB, he is certainly one of the fastest guys in the rosters. Anything 90+ is up there. Back to ratings...... rookies making debuts are subject to me using some interpolation of minor league numbers. Splits aren't given for minor leagues and even if they were, I wouldn't give a rook the same credit as a major leaguer who's proven. By the end of the year, when I do that roster, I'll have more data to work with on making adjustments where they seem due.
For example, he has a 52 - 57 / L - R contact split. If his current averages were to hold up the rest of the year, he would be assigned a 52 - 80 split. His power numbers would go up too. But it's hard to justify right now and I can't keep rosters living to include all of the adjustments. It would be a full time job.
