LAS VEGAS -- In what has become an annual tradition, Major League Baseball and its 30 clubs have organized a charity auction during the Winter Meetings, the seventh consecutive year the benefit has taken place.
This year's auction will support the Jackie Robinson Foundation and the Negro Leagues Museum, two important institutions that educate future generations of young people through honoring significant moments and individuals of baseball's past.
The auction is live on MLB.com/wintermeetingsauction from now through Thursday, when it will conclude at 10 p.m. ET. Items include special baseball experiences -- among them meetings with some of the game's biggest stars -- along with unique items donated by MLB and the 30 clubs.
Here are some of the notable experiences and items available in the auction:
• The 2019 MLB All-Star Experience will be highly coveted. The winning bidder will receive four tickets to all three days of events during the 2019 MLB All-Star Week at Progressive Field in Cleveland from July 7-9. The winning bidder will also receive four passes to an All-Star celebration held on Sunday, July 7. As an additional thank you for the winner's generosity, the top bidder and their guests will be able to watch batting practice for the T-Mobile Home Run Derby from the field at Progressive Field.
• Special meet and greets will be available with some of MLB's biggest stars, including Michael Trout, Aaron Judge, Francisco Lindor, Christian Yelich, Eric Hosmer and Shohei Ohtani, as well as some of the game's greats of the past, including Trevor Hoffman, Don Mattingly and Luis Gonzalez.

Since they began in 2012, the Winter Meetings auctions have raised approximately $1.15 million to assist a variety of causes, including cancer research, a youth baseball and softball field in memory of Shannon Forde, and a scholarship fund in memory of Katy Feeney.
The funds from the 2018 Winter Meetings Charity Auction will benefit the Jackie Robinson Foundation Scholars program as well as contribute to the Jackie Robinson Museum, which is currently under development in Manhattan in New York City and scheduled to open in 2019. The Negro Leagues Baseball Museum, which is geographically located near the Kansas City Royals MLB Urban Youth Academy, will use the funds toward much-needed repairs from recent damage and vandalism.
