I agree that Hanley is as you put killing us as he hasn't been hitting much at all. I am not sure why you say Ortiz is killing us and maybe I misinterpret your words here. Ortiz has been hitting the ball hard and in bad luck. Last night he walked 3 times and gave the likes of Hanley opportunities to do something. Nothing happened there. Hill and Shaw platooning against lefties/righties seems to make sense except Hill hasn't been hitting of late and Shaw does have more pop when he makes contact.
We do have some good hitters in the lineup, with Betts, Pedey, Ortiz, JBJ, Bogaerts (needs to make adjustments), Leon and Benintendi. To me, Hanley is the black hole and rally killer.
None of our lineup will matter unless we get better pitching.
