NASHVILLE, Tenn. -- The Giants' "gamers" aren't limited to players or the spirited-looking fans broadcaster Mike Krukow singles out on telecasts.

The collection of individuals dedicated to the Giants also includes Anita Sprinkles, who shows up every day to perform her tasks as the club's senior ticket operations manager, despite enduring cancer.

"She has to miss some time to go to chemotherapy treatments, but otherwise she's here," Russ Stanley, the Giants' managing vice president of ticket sales and services, said this week.

It's people such as Sprinkles, 46, who are being helped by the current Stand Up To Cancer initiative.

These Winter Meetings include an MLB.com Auction to benefit Stand Up To Cancer, which MLB has supported since 2008 as founding sponsor. Public relations representatives from all 30 clubs were inspired to act based on individual club members impacted by the disease, and they jointly organized the auction and announced it Monday in Nashville with MLB staff. Bidding closes at 8:59 p.m. PT Thursday, with more than 70 baseball-related experiences ranging from clubhouse tours by players to lunches with general managers to team bus rides to meet-and-greets with 16 Hall of Fame players.

Giants-related items up for grabs feature the greatest of the past and present.

A Hall of Fame package includes autographed baseballs from Willie Mays, Willie McCovey and Gaylord Perry, a cap signed by Orlando Cepeda and a jersey autographed by Juan Marichal. Each comes with a certificate of authenticity.

The Giants also are giving away a one-hour breakfast appointment for the top bidder and a guest in San Francisco with right fielder Hunter Pence, a noted breakfast connoisseur. Pence also will give his breakfast partners one autographed item apiece and will pose with them for a photograph.

The Giants' ticket office was rocked in November 2011, when Patrick Landers, who worked in group ticket sales, died of cancer. That heightened the employees' already high levels of awareness and sensitivity toward Sprinkles, who has worked for the Giants for more than 25 years.

Whenever the ticket department is forced to work overtime -- which has been often as the Giants have won two of the last three World Series -- or a co-worker plans a social function, Sprinkles is inevitably around.

"She doesn't want to miss a thing," Stanley said.
