Gunnar has already had 19 more PA than the #2 most (Adley), 22 more PA than the #3 most (Santander), 27 more PA than #4 (Westburg), and 29 more PA than #5 (Mountcastle). That is just over 1/4 of the season. Batting him 4th means that he will very often get only 4 PA per game instead of 5, and that 5th PA will take place at a critical time in the 9th inning. He hits a HR every 12.6 PAs (this year & every 19.9 PA career) so batting him second is coughing up 1-2 HR so far this season, 3rd or 4th is -3HR....and that's in just a little over 1/4 of the season. So, by moving him to 3rd or 4th you're taking away ~10HR over the course of a full season. Instead of putting him lower in the line-up, I'd like to see a higher OBP guy in front of him in the 9 spot. Gunnar has the tools to be a tremendous lead-off hitter.
