The Milwaukee Brewers came back for the second night in a row Saturday to beat the Chicago Cubs 5-3 in extra innings.  Keston Heura hit a two-run walk-off home run to cap off the dramatic comeback after Christian Yelich homered to tie the game at 3-3.   Freddy Peralta picked up the win in relief after giving up a home run in the top of the tenth to Albert Almaro.  The Brewers will look to sweep the Cubs in the three-game series Sunday with first pitch set for 1:10 pm at Miller Park.
