On Saturday, the hope was that Rhys Hoskins would sit for only a few days with a thumb injury. Unfortunately for the Milwaukee Brewers, the first baseman expects to miss much more time.Hoskins, 32, told reporters Tuesday that a recent MRI revealed a UCL left thumb sprain that could keep him off the field for about six weeks.”I’ll be doing my work in the quiet,” Hoskins said, “helping these guys as much as I can off the field so that we can continue our push toward the playoffs.”He suffered the injury during Saturday’s 4-2 loss to the Miami Marlins, during which he attempted to tag out a runner on an errant throw.”Unfortunately, the timing of the play didn’t allow me to tag him in a safer manner,” Hoskins said. “But, again, that’s a part of the game. That’s a part of the position.”
