One position in the batting order should be worth about 18 plate appearances (162/9). (That's assuming everyone has an equal chance of making an out, which of course isn't the case.) So the number 2 batter should come up about 54 times more than the number 5 batter. Take away a few for the days they don't play, and that's about 50. (Actually, LoDuca, as a catcher, would lose more than that.) If there are about 600 plate appearances, the difference is about a twelfth of that. Now here are some numbers out of a hat. I'm going to assume that both of them have good seasons by their standards. Say that David Wright, batting number 2, would create about 120 runs, and at number 5 would lose about a twelfth of that (10 runs), making his runs created 110. LoDuca, at number 2, would create about 80, and at 5, 73. 120 + 73 = 193; 110 + 80 = 190. The difference for the team, over the season, would be about 3 runs. Maybe one game. If LoDuca were to hit more like I'm afraid he will, the difference would be far more. But of course in that case he presumably wouldn't stay in the number 2 position.
