Prospect lists are always weird and subjective, but this was an especially weird year in which to assemble one. Not only are there new draftees to consider who haven’t yet had a chance to get their pro careers started, there are still Mariners prospects who, a year after being drafted, are yet to throw a professional pitch, as well as others who haven’t played stateside yet, thanks to the team’s tendency to slow-play college arms and international signings. This upheaval may show itself in some of our rankings priding proximity over ceiling in a way they might not in other years, or depending more heavily than we’d like on hazy pressbox-shot video from the alternate site and reading tea leaves from the box scores of the fall league.
