Here’s how Big Slick will offer thousands more seats for its 10th anniversary auction

Big Slick Celebrity Weekend is growing out.

The 10th annual charity bash to benefit the Cancer Center at Children’s Mercy Hospital has outgrown the Arvest Bank Theatre at the Midland and will move its big moneymaking event next year a few blocks over to the Sprint Center.

The change of venue, announced Thursday, will allow at least 5,000 people to attend the party and auction. Before, about 1,500 tickets were available at the Midland, which quickly sold out.

Organizers also announced the dates for the 2019 events: the celebrity softball game June 7 at Kauffman Stadium; the bowling tournament, red carpet appearances and free block party the morning of June 8 at Pinstripes in Overland Park’s Prairiefire; and the auction and party the evening of June 8.

Organizers are hinting about a change in the auction format next year, but details on that — as well as the celebrity guest list and ticket prices — won’t be revealed until tickets go on sale in the spring at bigslickkc.org.

Big Slick, anchored by Kansas City homeboys Rob Riggle, Paul Rudd, Jason Sudeikis, Eric Stonestreet and David Koechner, has raised more than $8 million to fight cancer since 2010. The anniversary event is poised to surpass the record $2.1 million raised this year.

Big Slick began as a celebrity poker tournament by Riggle, Rudd and Sudeikis. Koechner and Stonestreet joined as co-hosts in 2014. Guest celebrities who have dropped in include Selena Gomez, Will Ferrell, Jon Hamm, Olivia Wilde, Johnny Knoxville and John Oliver.

Children’s Mercy has used the money to explore genomics and personalized medicine for pediatric cancer patients, to expand its bone marrow transplant unit, to purchase early detection equipment and to add entertainment systems to every oncology hospital room.
