The most underrated 2B in the NL at least. Contact hitter, lots of line drives. His manager is a fan so he'll get AB's. Everyone has projected Hairston taking AB's away, but Walker isn't terrible against LHP. He'll get 450 AB's easy I think.
When Hairston does play LF, he may bat second, but w the potent 3-4-5 the cubs have, Walker batting 6-7 on those days may not be too bad.
BTW, Walker batting 7th last year = .291 avg, .927 OPS. Yeah only 55 Ab's, but not bad.
