Rapid Reaction: Brewers 5, Cubs 1

MILWAUKEE -- Here's a quick look at the Chicago Cubs' 5-1 loss to the Milwaukee Brewers on Saturday:

How it happened: Jonathan Lucroy improved to 6-15 lifetime against Edwin Jackson when he smacked a solo home run in the second inning. The Cubs tied the score in the fourth when Alfonso Soriano drove in Starlin Castro from second base. But the Brewers took the lead for good when the Cubs made two errors in the fifth leading to two unearned runs. First, Soriano dropped a fly ball -- that runner came around to score -- and two outs later Castro flubbed an easy grounder allowing another one to come in. In the sixth inning, Jackson threw away an easy double-play ball and the Brewers scored two more unearned runs. Other than the Castro run in the fourth inning, Cubs bats were silent against first-time starter Hiram Burgos and the Brewers' relief corps.

What it means: There's simply no excuse for many of the errors the Cubs have made this season. It has derailed more than just Saturday's game and more than one decent start from the team's rotation. A lack of focus seems to be the only answer, as these errors have come mostly on routine plays. The rest of the game, as well as Jackson's overall performance, is hard to judge when it comes apart so needlessly. After all, Jackson made one of the errors himself, leading to runs that don't count on his ERA. Maybe they should.

Key stat: Three errors in the game tied the Cubs with the Washington Nationals for the major league lead with 15, though the Cubs have played one fewer game.

What's next: The 5-11 Cubs try to avoid the sweep on Sunday when Scott Feldman takes the mound.
