A Reuters piece projects that this season, MLB attendance will drop 5-10% from 2008. In the article is some information from Lew Wolff, which indicates how well/poorly the A’s may do at the gate:

The A’s, who cut ticket prices by an average of 5 percent, are at 87 percent of their targeted budget for season-ticket revenue, where normally they would have finished by now, Wolf (sic) said. The club budgeted for a 9 percent decline in attendance.

Of the paid attendance, there will be additionally high numbers of no-shows due to already prevailing factors or the economy. If the A’s are way out of contention at the ASB, the expected fire sale, Holliday and all, will drive attendance down even further.
