Neil Walker‘s OPS versus left-handed pitchers over the last three seasons have convinced me that he should be platooned. (2011: .673 / 2012: .602 / 2013: .518) Others disagree. That makes the Pirates middle infield arrangement against lefties a good topic for a poll.
I would put Clint Barmes at shortstop against lefties and move Jordy Mercer over to second base. The Pirates, however, may have other plans. They are giving Barmes time at 2B this spring and he had much experience at the position during his days with the Colorado Rockies.
Josh Harrison is another possibility to platoon at 2B with Walker. He had only 42 plate appearances versus left-handers last season, but he did bang them around for a .981 OPS. His career OPS against them, however, is only .670 in 199 PA.
Harrison has been average in the field at 2B, posting a -0.1 UZR in 274 career innings.
