Hammondsnats - against a lefty like wolf, I'd put Desmond #2.
I'm guessing that Willingham might also be a good #2. Kind of like Nick with pop. I'd like to get him to the plate more times than he can as a #5.
After playing with the Musings optmizer a couple time this week, I have a hunch it would spit out:
Rodriguez (if you use 2007/ 2008 hitting)
For what it is worth, of the top 30 orders, all had Morgan 9th, Dunn leading off; 80% had wllingham 2d, the rest had him 4th; Zimmerman was 2d when Willigham wasn't, otherwise he was 4th (or 5th in 5 line ups). 3d - mostly Rodriguez or guzman; 7th - Livo in all but 4 line ups (8th in 4). Guz -mostly 5th or 3d, Pudge - 3d or 8th.
Optimum line up projected as 4.82 - 4.83 runs, actual 4.76. Probably takes a hit with Zimmerman batting 3d, but otherwise very close to optimum. Line up 15 or so was dunn, willingham, guzman, zimmerman, pudge, max, desmond, livo, morgan. As long as you maximize dunn, willingham, and zimmerman's at bats, and have morgan fairly close and before them in the order (or 9th), you'll optimize. Close to what riggs has done.
