Michaels' slam: Free Wednesday tickets

27-run output over series ensures 2,500 free seats for fans

ST. LOUIS - When Jason Michaels' seventh-inning grand slam cleared the left-center field fence in the seventh inning of Monday's game, it did more than propel the Pirates to a come-from-behind 5-4 win. With four runs scoring on the hit, Michaels capped off a weekend in which the Pirates scored a total of 27 runs to ensure 2,500 fans of free tickets to Wednesday's home game against the Astros.

The organization had set aside 2,500 seats in both left and right field, regularly priced at $24 apiece, as part of a unique promotion where with every run the Pirates scored in this four-game series against the Cardinals, $1 would be taken off that ticket price.

The Pirates followed up a four-run output in Friday's series opener with 14 runs scored on Saturday and four more on Sunday to lower the price per ticket to just $2 heading into Monday's contest. With Michaels' grand slam, the Pirates surpassed the 24-run mark, meaning that all of the tickets designated as a part of the promotion will now be available for free.

Now for the important details: All of these discounted tickets will go on sale at 9 a.m. ET on Tuesday morning. They will be available for purchase only through Pirates.com, and there is a cap set at eight tickets per customer.
