I think the lineup will shake out like this
Betts
Pedroia
Bogaerts
Ortiz
Hanley
Shaw
Holt
Swihart
Bradley
Here's what we get today:
Betts RF
Pedroia 2B
Bogaerts SS
Ortiz DH
Ramirez 1B
Sandoval 3B
Holt LF
Hanigan C
Bradley Jr. CF
So, same basic idea, and I think you've got it. Looks to me like Bradley is locked into the 9 hole for now, and Shaw/Holt/Swihart are pretty much just going to be swapped out for Sandoval/Young/Hanigan depending on matchups and people getting a chance to rest here and there.
Injuries will shake this up, obviously, but should they keep this relatively in tact, it really seems like JBJ is going to be the difference between a top-heavy line-up and one that can do serious damage.
Mookie/Pedroia/Bogaerts should get on base at a predictable clip (they combined for better than a .350 OBP last year) and keep the bases full for Ortiz and Hanley, who should have predictable RBI numbers as long as Ortiz doesn't fall off the face of the earth and echo his spring numbers, but that 6-7-8 run could make for a lot of easy innings. It's going to be hard for Shaw to remain patient with all the pressure on him and still was only a .327 OBP last year, Holt was a .311 OBP guy in his last 230 PAs last year, and Swihart was just at .319.
Swihart may improve, but it's hard to see Hanigan being much better than the .325 he's averaged over the last three seasons.
I've got a feeling Jackie's going to be up a lot with 2 outs and a guy on second. If he can just turn that lineup over and put up something like a .360-.375 like he's done in the minors, the Sox are going to score some serious runs. If he's a .310 OBP, it could get ugly at the bottom.
