Through the first ten games, attendance is down about 60,000. However, last year the home season opened with a weekend series against the Red Sox, normally amongst the season's biggest gates so that skews the totals a little.
As with examining anything in April it's too early to reach any kind of conclusions, but I'll be keeping an eye on this as the season progresses. Hopefully, the Jays presence at the top of the AL East will spark some interest in the next few weeks.
