The Milwaukee Brewers may be upgrading their closer.  Yahoo Sports is reporting that Milwaukee is in serious discussion with the Philadelphia Phillies to acquire closer Jonathan Papelbon.  Papelbon is set to make 13-million-dollars this season with a 13-million-dollar option for 2016 that is based on his performance.  The 34-year-old righty has a no-trade clause which includes 17 teams but it is unknown if Milwaukee is on the list.  Papelbon finished 52 games last season and racked up 39 saves with a 2.04 earned run average, his best ERA since the 2009 season with Boston.
