Week 4 Starts & Sits - All Starting Pitcher Matchups

9 months ago by Nick Mariano

We're now in "late April" and can start to talk ourselves into hot or cold starts being for real, including the juicy baseballs that are destroying pitchers! Welcome back everyone to our starts/sits column for Week 4. We here at RotoBaller set out to ease your decision-making with our weekly starting pitcher matchups and recommendations. In case you missed it, this is our sixth year now writing this weekly column, helping fantasy baseball managers pick the best pitchers weekly.

Below are the projected starting pitching matchups for Week 4, which will be updated as rotations are announced and tweaked. Injuries are claiming starters left and right, so this column will be continuously updated and adjusted for any postponements or rotation shuffles, reflecting official beat writer speculation for as many unconfirmed rotation slots as possible.

For every week of the fantasy baseball season, we look to analyze all of the projected starting pitcher matchups and put together our optimal lineups. Here at RotoBaller, we believe that it’s key to analyze every SP matchup, each and every week, to help determine which SPs to start/sit and identify some sneaky streams. Let's win some leagues!

SP Matchups & Start/Sit Recommendations

This weekly piece considers the pitcher’s opponents, their career stats against the opponent, some ballpark factors and historical splits. With all of this information, we then provide our start/sit recommendations for each starting pitcher matchup for the approaching week of fantasy baseball.

We'll now include a "Score" value that goes from 0-100, with 100 being a perfect start and zero being an easy sit. Setting 50 as the "Start/Sit" border, this should help you determine streamer candidates and add necessary context. Also, I've added a two-start pitcher table at the end that combines scores for you, with 100 being the general threshold (if 50 is for one start, 100 is for two). Individual games are listed in case one great and one poor matchup requires attention. We're also working on a spreadsheet that will show historical accuracy that will eventually be linked at the end of the article. Now, time to dive in!

This column was last updated on Saturday, April 27th, and will be updated daily as more rotations and starters are announced through April 28th.
