CHICAGO -- Here's a quick look at the Cubs' 4-2 victory over the Houston Astros:
How it happened: Down 2-0 behind Carlos Zambrano, the Cubs used a four-run fifth inning to take command of the game. A nice combination of long ball and small ball pinned the loss on Houston starter Bud Norris. In the inning Darwin Barney's heads-up steal of third base set up a sacrifice fly by Starlin Castro. Alfonso Soriano hit his first home run since June 19, and Aramis Ramirez's 13th home run in his past 26 games put the Cubs up 4-2.
What it means: The Cubs' 24th comeback win of the season gives the Cubs another game of separation from the last-place Astros.
