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 inspire confidence (or lack thereof) in your decisions to start or sit certain pitchers.

Please note that beyond the usual "Start" and "Sit" labels, we've expanded on the old "context-dependent" section to break it down further with "Lean Sit," "Lean Start," and true 50/50 "Coin Flip" designations. 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. Still, some situations are fluid, and we update ASAP to reflect accurate information. At least we're on the other side of chaotic events such as the trade deadline, but these teams always find ways to keep us on our toes.

The "starts" category includes pitchers you'd likely start in every league. The "sits" are pitchers you likely sit in every league.

The 40-60 range will mean 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.

Here are your starts and sits for what we're calling Week 1 of the fantasy season and covers March 25 through March 29.
