Fantasy Baseball: September schedule quirks for savvy managers to know

Here are some schedule quirks that wise fantasy managers will want to know. This data covers the four-week stretch that begins next week, which includes the final week of the fantasy regular season and the playoffs in leagues with default Yahoo settings.

If there is one schedule to know, it's that of the Mariners. From September 3-20, Seattle plays 10 of its 16 games against the Athletics and Rockies , who rank 29th and 30th respectively in ERA. Even better, seven of those games will be played at Sutter Health Park or Coors Field, which are the two most inviting parks for hitters. Seattle is the only club which will get to feast on both pitching staffs during September.

Roster moves: Dominic Canzone (20%) has been one of the most under-rostered players on this site all season and could be a league-winning player during September. After all, despite being seventh among Seattle hitters in roster rate, he ranks third on the team in homers, third in RBI and second in OPS. Cole Young (14%) is the other Mariner to add. The widely available infielder ranks second on his team in both RBI and runs, and 5th in homers.
