Before setting your Week 23 Fantasy baseball lineups, you need to see what our advanced computer model has to say. When it comes to ranking players, the model beat human experts in Fantasy football last season when there were big differences in ranking. And the model was closest-to-the-hole overall, meaning it best pinpointed where every player would finish each week.

Last week, the model was extremely high on Orioles second baseman Hanser Alberto, saying he'd finish as the 11th best player at his position despite a market ranking of 33rd. The result: Alberto has recorded three hits, two home runs, four runs scored and six RBI so far in Week 22. Anybody who had him in their lineup was well on their way to a huge week.

Now the model, which simulates every pitch and every at-bat 10,000 times, has revealed its rankings for Week 23 (Aug. 26 to Sept. 1).

For Week 23, we can tell you Astros outfielder Michael Brantley, the third-best player at his position according to market value, stumbles big-time and doesn't even crack the top 20. 

One player the model is high on this week: Reds shortstop Josh VanMeter. He's the model's No. 4 shortstop in the Week 23 Fantasy baseball rankings even though he's owned in just 25 percent of CBS Sports leagues. VanMeter is hitting .333 since the All-Star Break.

The model is also calling for a surprising shortstop you aren't even thinking about to finish in the top 10 of its Week 23 Fantasy baseball rankings. This pick could be the difference between winning big and going home with nothing.

So who should you sit and start in Week 23? And what surprising shortstop could lead you to Fantasy glory? ... Join SportsLine now to get Fantasy baseball rankings for every single position, and see which surprising shortstop comes out of nowhere to crack the top 10, all from the model that out-performed experts big time last season!
