AFL stats have been described as "less than irrelevant" but it is still good to see some Cubs succeeding somewhere. Lake has put up a .379/.438/.707 line so far in the AFL.
I have not been able to find any scouting reports saying anything other than he is just hot right now. This is a guy who struck out 109 times between A+ and AA ball last season and was buoyed by a .384 BABIP at A+ ball. He has struck out 14 times while walking only 4 times this fall so it doesn't appear that much has changed in his approach at the plate.
