For every strikeout a Swallows' pitcher racks up in 8 games between 7/27 and 8/5, the Swallows will subtract 30 yen off the final cost of a reserved seat A ticket for a three game series against the Yomiuri Giants in September (9/14 - 9/16).
The tickets will become available for sale at Circle K / Sunkus convenience stores beginning on 8/14.
Swallows' pitchers are currently averaging 6.7 strikeouts per game. Assuming they keep that ratio up, the discount will be worth 1,600 yen. The cost of reserved seat A tickets against the Yomiuri Giants is 3,900 yen. After the discount, fans will be able to purchase the tickets for 2,300 yen.
