Starts and Sits - All Starting Pitcher Matchups for Fantasy Baseball (September 25 - October 1)

Michael King - Fantasy Baseball Rankings, Draft Sleepers, MLB Injury News

Fantasy baseball starts/sits advice for all starting pitcher matchups for September 25 - October 1 (2023). Set optimal lineups with Nick's start/sit recommendations.

It's the last call, RotoBallers, so let's finish strong with our starting pitcher starts/sits for fantasy baseball Week 27 - from Monday, September 25 through Sunday, October 1.

For 11 years running, we have been writing this Starting Pitcher Starts and Sits series every week right here at RotoBaller. I'm Nick Mariano, returning to the helm after taking a couple of years off. There's plenty involved under the hood here and lots of TLC goes into this piece each week. We get tons of great feedback on it every year.

If you're new here, read below to get caught up on what this all is and how to best use it. We know this week will be wacky, what with shutdowns, shuffling rotations for playoff schedules, and so on. We will be scouring the wire for info to help you make the best fantasy baseball starting pitcher lineup decisions!

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, 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 we're on the fence and it's up to you to decide based on your league settings. How deep your league is, which roto/points categories, and so on. Let's get to it! Here are your starts and sits for what we're calling Week 27 of the fantasy season, which covers September 25 through October 1.

 

Week 27 Start/Sit Recommendations

Updated start/sit recommendations for this week's MLB games. This chart is updated daily as probable starters are constantly changing with game postponements, injuries, and other events. If you can't see the chart below, click here to see the starts/sits on a separate page:
