One thing to consider, when discussing AVG and OBP is the difference when you subtract AVG from OBP (OBP - AVG). The larger this gap, the more walks the player is taking. This is a good thing and a bad thing, depending on where they bat and your point of view. Consider two players have an OBP of .350. Player A has an AVG of .320 and player B has an AVG of .280. It's apparent that plater B walks quite a bit more. It's also apparent player A hits the ball better, as a greater part of his OBP is made up from AVG instead of BB. Now consider they have similar SLG as well, so the extra hits player A is generating are basically singles. It would also mean he doesn't hit as many extra base hits as player B, by a slight margin potentially. When deciding who should bat in front of who, you need to consider this. You want player B to bat in front of player A. Player B will draw more walks and get to first. Player A will more likely get a hit and go to first. If player A was on first and B walked, A would be on second. If player B gets to first and player A gets a base hit, player B can likely get to third. So my point is a walk isn't as valuable as a basehit in terms of moving base runners around. This is why, if you move Weeks down the lineup, he should bat in front of Estrada. Estrada hits the ball a lot and is able to move runners around the bases. Weeks walks a lot more (and is quicker). So you want Estradas bat moving him around.
