Before setting your Week 27 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 Chicago White Sox shorstop Tim Anderson, saying he'd finish in the Top 5 at his position despite being started by about 75 percent of owners. The result: Anderson hit .375 for the week with two home runs. 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 27 (Sept. 23 to Sept. 29).

For Week 26, we can tell you Atlanta Braves second baseman Ozzie Albies, the third-best player at his position according to market value, stumbles big-time and is barely in the Top 20.

One player the model is high on this week: Philadelphia Phillies third baseman Maikel Franco. The six-year veteran faces the Nationals this week, a team Franco has hit .302 against this season with four home runs and six RBI. 

The model is also calling for a surprising shortstop you aren't even thinking about to finish in the top 10 of its Week 27 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 27? And what surprising shortstop could lead you to Fantasy glory? ...
