Starts and Sits - All Starting Pitcher Matchups for Fantasy Baseball (September 9 - September 15)

The final stretch of the fantasy baseball season has found us, so let's keep battling with our starting pitcher starts/sits for fantasy baseball Week 25 -- Monday, September 9 through Sunday, September 15. We continue to keep tabs on rookies getting called up in September, rehabbing pitchers preparing for the playoffs, and teams resting key arms. Stay tuned for every start/sit call and potential two-start choices for your lineups.

For 12 years running, we have been writing this Starting Pitcher Starts and Sits series every week here at RotoBaller. I'm Nick Mariano, here to lead you through the 2024 season. All sorts of firepower and TLC go into supplying this piece each week. We get tons of great feedback on it every year.

If you're new here, read below to catch up on the aim of this piece and how best to use it. Best of luck with your fantasy baseball starting pitcher lineup decisions. Let's jump in!

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. September ramps up the day-by-day chaos so check back often!

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 25 of the fantasy season, which covers September 9 through September 15.
