We've seen the first big wave of promotions this season, and from here on, teams have secured an extra year of control and have dodged a fourth year of arbitration, so there are no more service-time games to be played. There are a handful of prospects still in the minors whom many of you have been stashing all season. There are others who were promoted and then sent back to the minors, but who still warrant stashing in certain formats. One big name has emerged as a quality stash in deeper leagues. Another dozen prospects need to be closely monitored, as they are not quite stash-worthy, but could become relevant in redraft leagues in short order. There are also a handful of big names who could still make it up this year, but are either unlikely to debut in 2019 or are unlikely to be up in time to provide significant fantasy value.
In this piece, I attempt to analyze when we could see these players, or what it would take for them to get the call. Within each subgroup, players are listed in the order they are ranked on the recently-updated top 400. In next week's piece I will provide the annual Short-Season/Rookie Hitter Index article that should serve as a key tool identifying this year's breakout teenagers in the short-season leagues, most of which begin play this weekend.
