I see where Dusty Baker said, "I don't think so", when asked if he thought EE would be returning to the Major League club to begin Tuesday's home stand. He said, "He's got a different swing than Joey", inferring I guess that EE's swing requires more timing or something like that.
I wouldn't think it's going to be too much longer after that. Why would a hitter need more than 10 days in the minors? Perhaps the hand swells every night, or swells after a few days, and they want to make sure there isn't any swelling at all, even after a week of playing, before the move him up for good this time.
