CINCINNATI (CBS / AP) — Brandon Belt hit a three-run homer, and Buster Posey added a two-run shot off Jason Marquis on Friday night, leading the San Francisco Giants to a 10-2 victory over the Cincinnati Reds in a game played uninterrupted while an outfield smokestack burned for an inning.

One of the two riverboat smokestacks that shoot off celebratory flames and fireworks caught fire in the top of the sixth because of a malfunctioning propane valve. Flames shot from the top of the smokestack and spewed dark smoke until firefighters extended a ladder from outside the ballpark and sprayed it.

Madison Bumgarner (4-2) gave up eight hits in seven innings, including solo homers by Zack Cozart and Billy Hamilton.
