There's a lot of moving variables, It's more probably than not we see any one of these guys next year rather than this year. Development aside, a lot depends on the big league club.
Here we stand, 2.5 games out of the playoffs. It feels like everytime they get some momentum they fall off, and everytime the start to lose it they string together a few wins. If they get healthy, perform, and are in the playoff hunt. There's not much need to rush Teel with the Wong/McGuire duo, or Anthony with Duran/Rafaela/Abreu, or Mayer with Rafaela, Hamilton, Valdez on the roster.
But if anyone one of those guys is mashing in AAA come late July or early august and the Sox think they're ready or close to it and someone like Wong/Rafaela go down could I see one of those guys being called upon to come up if the team thinks they may be ready to contribute? Absolutely, and I still think one of them may even get a cup of coffee this year.
