I agree, but there is one issue. He has to decide on Gomes within 2 weeks of the WS. Unless he can swing a deal for a LFer before then he might not want to risk losing him. There may be a market for him that exists and if they don't exercise, he may not want to be left with Heisey/Nix if it ends up that he can't swing a deal.
I can see him exercising and saying all the right things while still looking to upgrade or find a platoon partner. Worst case is that he has a $1.8MM pinch hitter 4/5th OFer who hits lefties very well and who appears to be positive in the clubhouse. That's not a bad thing.
