Before setting your Week 4 Fantasy baseball lineups for the 2023 MLB season from April 17-23, you NEED to see what SportsLine's advanced computer model has to say. When it comes to ranking players, SportsLine's model regularly beats human experts, especially when there were big differences in ranking! That could literally be the difference between winning your league or going home empty-handed.

Now the model, which simulates every MLB game 10,000 times, has revealed its latest Week 4 Fantasy baseball rankings.

One player the model is high on this week: Diamondbacks first baseman Christian Walker, who hit a career-high 36 home runs last season, ranking him among the top 10 first basemen for Week 4. And a massive shocker: White Sox starter Dylan Cease, the 2022 AL Cy Young runner-up, doesn't even crack the top 50 at his position! He's a player to consider leaving on the bench.

The model is also calling for an under-the-radar outfielder to finish in the top 10 of its Fantasy baseball rankings, ahead of stars like Aaron Judge and Ronald Acuna Jr.! This pick could be the difference between winning BIG and going home with nothing. You ABSOLUTELY need to see who it is before locking in your lineups.

So who should you start and sit in Week 4? And which surprising player could lead you to victory? ... Join SportsLine now to get Fantasy baseball rankings for every single position, and see which shocking OF comes out of nowhere to crack the top 10, all from the model that has out-performed experts big-time!
