OTOH, you are putting a .300 OBP guy in front of your best hitter.
Yes, but the point of hitting a lesser hitter 3rd according to "the book" is that he comes up with the bases empty quite often. The order of importance for not making outs (highest OBP) supposedly goes #1, #4, #2, #5, #3, #6, #7, #8, #9.
