Prior to the home opener, manager Dale Sveum said the Cubs (2-5) have to step up as an offense and start getting some key hits.

They were unable to do so until the ninth inning Monday afternoon, falling to the Brewers 7-4 in front of 40,083 at Wrigley Field.

At the start of the game, the wind was blowing straight out to center at almost 25 mph. Brewers first baseman Martin Maldonado took advantage in the first inning, dropping a two-out, three-run double in over Nate Schierholtz's head in right field.

By the middle innings, the wind was blowing out only to right, and in the bottom of the ninth, as the Cubs were mounting a rally, the wind was actually blowing in from right field.

"They got four and the wind shift cost us four," Sveum said after the game. "But that's Wrigley."

The Cubs couldn't put together much offensively in the early going, scoring their only two runs on a homer by Welington Castillo in the second inning. But in the ninth, they started chipping away, plating two and loading the bases for Starlin Castro with two outs.

The All-Star shortstop drove a ball to the warning track in right, but it fell harmlessly in Norichika Aoki's glove to end the game.

"I hit that ball good," Castro said. "The wind changed and started blowing in. If I would have hit that ball in the first inning or second inning, it would have been a homer. But even with the wind blowing in, he caught it on the warning track."
