When there were only two baseball games played on Monday I was reminded of the importance of filling in your lineups on days when you might have holes in your roster.  If you were to pick up just one player to fill in your  roster every Monday and Thursday of the baseball season you'd have 52 extra games played.  That's roughly 120 extra AB.  By doing this you could expect an extra 6 HR, 18 runs, 18 RBI, and 3-5 steals.  That could easily mean 2-5 points in your league and possibly the difference between 1st place and 3rd place. 

If you choose you Monday/Thursday players wisely you gain even more of an advantage.  Many players have strong splits that you need to be aware of when choosing your pick ups.  In 12 team mixed leagues you can expect many of the following players available as free agents.  Check out their splits.  If you pick them at the right time you can really cash in.
