TORONTO — In a city where the last playoff baseball game took place 20 seasons ago, the Blue Jays have been in first place for more than a month. The last time that happened, in 1993, Toronto won the World Series.

Toronto has been wandering in the postseason baseball desert for so long, this season would seem like a deliriously unexpected stroke of good fortune, especially since last year’s team finished in last place.

So Blue Jays tickets must now be a hot commodity, right?

In fact, the opposite has occurred. Blue Jays home attendance is down more than 4,300 fans per game compared with the same period a year ago, a decline that is the second largest in the major leagues.

At Tuesday night’s game against the Yankees, the Rogers Centre stands were more full than usual, but the surplus included thousands of Yankees fans, some of whom had made the drive from upstate New York. By the second inning, they were chanting, “Let’s go, Yankees!”
