The San Francisco Giants’ victory in the National League Championship Series and spot in the World Series have sparked an orange glow throughout the city – and a green one in local businesses.

The impact of baseball fever was unmistakable at the Stonestown Galleria this week. The clearest sign was the line of eager fans waiting for a chance to get in to the Giants Dugout store and pick up a commemorative baseball cap, a Buster Posey jersey, or perhaps something classic in orange and black.

At 4:35 Tuesday afternoon, 27 people waited outside the Dugout store while about 15 others shopped inside, behind a store employee posted at the door. Less than half an hour later, the line was nearly a dozen people longer and a crisply uniformed mall security officer had taken up a post in the doorway alongside the Dugout employee.

At 8:45 Tuesday evening – just 15 minutes before closing time – the line was 20 people long.

While the queues weren’t as long at other stores in the mall, those businesses that offered Giants-related merchandise seemed to be enjoying an uptick in sales.

“Anything with an ‘SF’ on it flies,” said Mark White as he sat on a wooden stool at the Wireless Accessories kiosk store on the mall’s first floor, holding an iPhone sporting a black case emblazoned with those two letters in orange.

White said iPhone cases like the one on his phone cost $25, and have been a popular item. Sales at his kiosk had gone up by about 20 percent recently, he estimated.

At the Foot Locker shoe store on Stonestown’s upper level, a clerk who gave his name as David said that while his store hadn’t seen the same demand as the Dugout store, Giants caps bearing the 2010 World Series  logo had been a popular item at $35.99.

Half the people he had spoken with in the store were looking for Giants merchandise, David said. He guessed that amounted to an increase of about 25-30 percent since the NCLS.

“A lot more people are coming in for it,” he said.

The Champs Sports store at the other end of the mall had a variety of shirts and caps on display behind the counter, and a steady line at the registers. The store manager asked a reporter to come back nearer to closing time when he might have time to talk. But at 8:50 that evening the line was even longer than it had been in the afternoon.
