Jeff Francoeur of the Royals is crushing lefties with a 1.006 OPS this year (.764 OPS overall). He'd make a great platoon option with Jones at worst and an upgrade to the lineup overall if Jones moved to first full time. He's signed to KC for 2.5 million this year with a mutal option for 4 mil for next year.
I'm not sure what level of prospect would be needed to acquire him but I'd gladly deal Gorkys for him. He'd add some nice balance to the lineup when everyone's healthy with Cutch, Tabata, and him coming from the right side of the plate and Jones, Alvarez, Walker, and Doumit coming from the left side. In fact, I'd prefer him over Carlos Pena.
