The #5 hitter is the same as the #4 hitter but the better one bats 4th. And the #9 hitter is the 'secondary' leadoff hitter. The same kind of player as the leadoff guy but maybe a 2nd year player or some other trait that knocks him down a notch. He's gotta "set the table" once the game gets into the middle innings. The 8 hitter is the worst guy... your Gerald Laird or Adam Everett's of the world.
