Prospect list season continued Friday with the release of Kiley McDaniel’s farm system rankings with the Oakland Athletics coming in at No. 19 on the list. If you missed it, Keith Law had the A’s system ranked 27th earlier this week. All prospect lists and system rankings are subjective so there is ultimately no right or wrong answer. They are fun though and McDaniel incorporates surplus dollar values for each future value tier of prospect into his rankings. Through that lens, the A’s fared a little better jumping from 28th last year into the middle tier at 19.
