There was a fire in the ballpark, and the San Francisco Giants were on fire on the field of play against the Cincinnati Reds.

Brandon Belt hit his first home run of the season, a three-run shot in the top of the first inning and the Giants defeated the Reds 10-2 at Great American Ballpark.

Buster Posey hit his team leading sixth home run of the season, as the Giants bounced back from a demoralizing loss in the opener of the four-game series, when Marlon Byrd hit a solo home run off of Sergio Romo in the bottom of the eight inning to give the Reds a 3-2 victory.

A bizarre thing happened in the top of the sixth inning, when one of the two riverboats smoke stacks that celebrate Reds home runs caught fire due to a malfunctioning propane valve.

Madison Bumgarner gave up eight his in seven innings of work, as he improved his record to 4-2 on the season.

Jason Marquis lasted a season-low three innings, he allowed a season-high six runs in the eight-run loss.

Joe Panik extended his career-high hitting streak to 11 games, as he singled in the top of the first inning.

Hunter Pence will rejoin the team on Saturday after doing a rehabilitation assignment with the Sacramento Rivercats, where he was recuperating after breaking the hamate bone in his left arm.
