And it's going to have to be every time, because in '04 he was walked 232 times (an all-time record by a mile) and still managed to hit 45 HRs.
He's determined to pass Ruth's 714 at all costs, and unfortunately he'll accomplish that. Whether or not he can catch Aaron's 755 is antoher question entirely.
Will he? Since MLB started testing, he managed to play a total of 14 games (albeit hitting 5 home runs). But it's true, to hit the last few, he'd go to the Devil Rays to be DH.
