The annual Mystery Autograph sale, organized by the Seattle Mariners Wives, is Friday, July 7, when the Mariners take on the Oakland Athletics. Game time is 7:10pm.
Fans can buy a sealed paper bag with one baseball, autographed by a Mariners player or manager Scott Servais. The cost is $50 each. Each baseball comes with an MLB Authentic hologram sticker.
Proceeds from the sales will benefit Mariners Care, the team's nonprofit foundation which supports primarily youth-oriented charities throughout the Pacific Northwest. Since 1991, Mariners Care, in partnership with the team's corporate partners, has helped raise over $23 million.
The autographs will be available on the Main Concourse at Section 128 and on the Suite Level. Last year's sale raised $17,500.
Friday is also Mariners Snow Globe Night, presented by Emirates Airline. The first 20,000 fans through the gates will receive, at random, a snow globe of either Safeco Field or the Kingdome.
Tickets for the Mariners homestand and all remaining games at Safeco Field are available online at Mariners.com/Tickets, and without a service charge at the Safeco Field ticket office and Seattle Mariners Team Stores (downtown Seattle at 4th & Stewart, Bellevue Square, Southcenter and Alderwood Mall). Tickets are also available by phone at 1-888-SEA-HITS.
