He certainly appears ready and was selected to play in the Olympics qualifying round which will keep him off the roster until August. Casas is being treated similarly, although in his case he hasn't played at the AAA level as yet. Meanwhile, the Sox had a surprisingly effective, nearly ist third of the season and are in the hunt. They did this with a very weak hitting Cordero in the lineup, a Chavis for s short time who appears to still be a sucker for a high fastball, a right fielder who is good defensively but is weak hitting against right handed pitching and Dalbec, who appears to be lost at the plate.
I didn't understand why they refused to bring Duran up. This business about him not being ready defensively sounds like a lame excuse. The real reason may be to give him a chance to play in the Olympics, at the expense of the ML team. In addition, one could question why Casas shouldn't be given a try while letting Dalbec be platooned. Of course we also have Houck waiting in the wings for another chance. In his case, he had a slight injury so his help was not available.
If the Sox feel that they can't be competitive this year, then not trying hard to solve their shortcomings makes sense. Based on their record, I really think they should have made moves which at least have a shot of making the club better.
