Fantasy baseball players of all kinds make tough choices every day. Whether you're locking in a DFS lineup looking for a potential 3-HR bat or need a solid innings-eater for your season-long points league to help win your matchup, you need as much information as you can get every day of the MLB season. That's where X factors comes in, using a proven projection system known as THE BAT, which uses methodologies like those employed in major league front offices to project players in each day's matchups.

We'll provide updated projections every day, so check back before setting your daily lineups.

Sunday's pitching slate is Chris Sale and Gerrit Cole -- nearly indistinguishable from each other -- and then a whole lot of nothing. Domingo German, Carlos Rodon, and even German Marquez are among the best "under the radar" plays.

The Rockies are an elite offense, but face a good pitcher in Caleb Smith. As a result, they're surpassed by the Red Sox today. The Astros and Twins are also great stacking choices.
