Marco Estrada walked out to warm up and saw the wind blowing straight out at Wrigley Field, a rare sight for an April date at the iconic neighborhood ballpark. It was an unfortunate development for the right-hander, but he made it work in a big way for the Milwaukee Brewers. Estrada pitched seven effective innings and doubled home a run Monday, helping the Brewers stop a five-game slide with a 7-4 victory over Chicago in the first game of the season at the Cubs' longtime home.
