Start/Sit Data Overview
Ahead of each week of the fantasy baseball season, we publish the table below. We have the probable starters for every game of the week and a grade for them on a 0-100 scale. The intent is to give you advice and to inspire some confidence (or lack thereof) in your decisions to start or sit certain pitchers.
Please note that beyond the usual "Start" and "Sit" labels, there is a third category called "context-dependent." This is because different leagues call for different actions, and those in start-sit purgatory may be worth the gamble to some. Also, we put the arms best projected to start or get bulk innings or actionable arms who may return from the injured list or be called up, but some situations are fluid, and we update ASAP to reflect accurate information.
The "starts" category includes pitchers you'd likely start in every league. The "sits" are pitchers that you likely sit in every league. The "context-dependent" means it is close, and it's up to you to decide based on your league settings or team needs (wins, strikeouts, etc.). How deep your league is, which roto/points categories are scored, and so on. Let's get to it! Here are your starts and sits for what we're calling Week 21 of the fantasy season, which covers August 12 through August 18.
