The calendar has turned a page to August and, with just about a month left in the minor league season, I thought it might be a good time to take a look at the A's minor league leaders in a few key hitting and pitching categories. A minimum of 200 at-bats is required for the hitting categories and a minimum of 90 innings is required for the pitching categories, with the exception of saves, of course. I've included players from all four of the A's full-season affiliates - Nashville, Midland, Stockton and Beloit - and the stats are complete through games of Sunday.
