scutaro
is what i'd go with. I'd go with scutaro at 9th, due to the fact he has a high OBP. Ellsburry is a career .290-.295 hitter, so I think the 7 hole would do him well. By the time he bats he will often times have men in scoring position in which a single will do alot of damage.
Redsox have a very scary offense this year, if Saltamacchia lives up to this potential they are by far the most potent offense in the AL, imo.
