Now I get your question. In fantasy, you don't set a "line-up" like a manager would. You just pick the players that are going to start. It doesn't matter what order they're in. You just get the stats that your starters put up in their games. So if Pierre goes 2/4, scores a run, steals a base, has 0 RBI and 0 HR on 1 day, you'll see a R, a SB, and a .500 AVG for that day. Over the course of the week, it'll total up R and compare them to the "team" you're playing (KMac in the first week). Whichever "team" has the most Rs will essentially get 1 W (on the main page, you'll see W-L-T, meaning wins, losses, ties). Same for RBI, HR, and SB. AVG will be the average of all your starters. Do the same for pitching stats. At the end of the week, all of them will be compared and it'll basically be considered 10 "games" in a way. So if you have more R, RBI, and W, and a higher AVG and ERA than KMac in the first week, but that team has more HR, SB, S, Ks (from pitchers) and a higher WHIP, your teams will each be 5-5 after the first week. If you click on your "Match-up" link from your home page during the week, it will show you how you are doing against the team you're playing. So if you are trying to decide whether to start Murton or Alou and you see that you are behind by 1 or 2 SBs, you'd probably choose Murton b/c he's more likely to get steals than Alou. Match-ups run Sunday to Saturday.
