Cubs 6, Diamondbacks 5

Here's a quick look at the Cubs' win on Tuesday afternoon.

The good: Tyler Colvin’s first homer of the season and bases-loaded RBI walk helped the Cubs get over .500 for the first time since 2009. Starter Andrew Cashner threw 5 1/3 innings of two-hit, one-run baseball before leaving the game with a stiff shoulder.

The bad: Cashner went for an MRI on his shoulder following the game. Results are expected on Wednesday.

Beyond the box score: Left-hander Sean Marshall stepped in to assume the closer role. He earned his third career save due to the fact that both Kerry Wood and Carlos Marmol were unavailable on Tuesday (both had thrown three days in a row).

Next: Ryan Dempster will make his second start of the 2011 season against Arizona’s Armando Galarraga.
