This feature does not keep track of how many starts you have left for the week. What it does is it shows you how many "possible starts remaining" you have on your current roster. For example, I have had 9 starts going into today's game and my PSR reading was 3. This tells me I have three pitchers on my roster that were going to start today (or the rest of the week). So if you look at your roster I bet you do not have any starters that were going to start in major league games today.
