In addition to his nice K/BB for a young player he has been very consistent. He has hit 7,7,5,9,6 (august) home runs in the months since starting the season. His lowest BA posted was .266 for a month, with .275 another month and no other months under .290. This consistency means there is little chance of this being a fluke. Further, his .285 BABIP and 21.3% HR/FB do not give great cause for alarm due to luck or unsustainable performance. This is why he's a great keeper prospect especially if he is undervalued coming into next season.
