Marco Estrada pitched four scoreless innings allowing only one hit, Carlos Gomez hit a home run and Taylor Green had a couple of hits as the Milwaukee Brewers beat the Chicago Cubs 4-3 in Cactus League play Sunday.   The Brewers played nine consecutive days and get their first day off Monday.  They'll need it as injuries continue to mount.  Corey Hart and Mat Gamel have both been out with knee surgeries and on Saturday, Aramis Ramirez jammed his knee sliding into second base and limped off the field.  It appears to be just a bad knee bruise and he's listed as day to day.  Yovani Gallardo complained of a sore groin which could limit his ability to pitch in the World Baseball Classic and Ryan Braun missed the entire weekend with a bruised knee.
