SAN FRANCISCO -- She's become a fixture on the video board here at AT&T Park and now that the Giants are in the World Series, on national television, as well.

She's 86, so it's safe to refer to Rosalie Alioto as a senior citizen though she still brings enough energy to the ballpark to be bouncing up and down, waving her fist in the air, cheering loudly whenever the home team lights things up.

"I love the Giants," she said. "I love baseball. That's my thing."

In truth, Alioto is part of the Giants family both figuratively and literally. Her son Mario is the team's senior vice president for marketing. Her grandson Marco is one of the team's batboys.

But while the connection is there, her enthusiasm for baseball is genuine and goes back to an era before the Giants arrived on the West Coast.

Alioto was born in Sicily, then came to the United States with her parents at age 11. The family settled here, and it didn't take long before she began going to baseball games with her father.

Before the Giants arrived, she considered herself a New York Yankees fan. But in 1958, she had her own major league team to follow -- first at Seals Stadium, then Candlestick Park, then AT&T where she has one of the best seats in the house, front row of the club level between home plate and first base.

Wednesday night, she was there with her daughter-in-law Kelly, granddaughter Giuliala and grandson Tony.

When Pablo Sandoval hit his third home run of the night to give the Giants a 6-0 lead over the Detroit Tigers, she was as animated off the camera as she was on the video board.

All of which has made the diminutive Alioto -- "4-foot-10 and I'm shrinking" -- a celebrity in her section.

"She's great," said Monty Woods, who shares the same row and disclosed a marketing secret: Though Rosalie shows up for every day game and night games during the playoffs, sometimes she appears on the video board when she's not in the building.

It's called stock footage, a not uncommon practice.

"They show her when she's not here," Woods said. "I'll look up there and see her and then -- wait! -- I'll look to my right and she isn't there."

The Alioto name is a politically powerful one in San Francisco, but Rosalie said the former mayor and supervisor were only distant cousins.

"We're all from the same small town," she explained.
