A few things to think about Bell. He has been heating up the last seven days. Also, today is June 15th. I heard this on Foul Territory last week the first date which a FA who signed in the offseason could be traded was June 15th. Since they signed him to a $7M contract, I foresee the only way Bell is leaving is through a trade. He will need to perform better in order to be traded which means he will need to be in the lineup. If you want Bell gone, the best thing you can do is hope for him to get hot for the next month that another team is willing to take a flyer on him.
Now to the topic at hand, Fedko. I can see them playing Fedko more in CF than Kriedler when giving Buxton a day off. They need Kreidler to play more at SS as Gray has seemed to have fallen off, both offensively and defensively lately. Fedko likely hit the lottery in terms of opportunity. I think, under normal circumstances, this roster spot would have already been taken by one of Jenkins, Rodriguez, or Roden. Since they are both on the recovery train, he gets a shot prior to them coming back.
