The already-strong Milwaukee Brewers bullpen added another tested arm when left-handed reliever Boone Logan was activated Thursday.  Logan pitched to one batter in the 5-2 victory at Colorado.  He’s been sidelined since spring training with a strained triceps.  Logan signed a free-agent deal with the Brewers during the off-season.  Milwaukee’s bullpen currently has the second-best earned run average in the major leagues at two-point-61, trailing only Arizona.
