Taylor Swift curse: Blue Jays fans fret over pop singer's weekend concerts

American chart-topper Taylor Swift is playing two sold-out shows at the Rogers Centre in Toronto this weekend, and this has some Blue Jays fans worried. Will the Jays fall victim to what some see as the T. Swift curse?

Number crunchers at ESPN have looked at the records of baseball teams whose home stadiums have hosted concerts on Swift's 1989 tour. And the results aren't pretty. 

The legend of the Taylor Swift curse seems to have begun in Washington, D.C., where the singer performed in July. When the Washington Nationals next played at their home ballpark, the lights went out. Three times. 

Play was delayed after the first two power interruptions, but after the third, the game was suspended and resumed the next day. 

Nationals pitcher Max Scherzer noted the perceived connection to Swift in a tweet posted that night. 

The Nationals' season has been disastrous since then, culminating in the dugout fight between pitcher Jonathan Papelbon and teammate Bryce Harper and the team's elimination from the playoffs. 

The next team apparently hexed by the power of T. Swift was San Diego Padres, who lost 18 of 29 games after her concert at Petco Park on Aug. 29. They're also out of the playoffs.

And then, there's the Houston Astros. Back in July, the team moved a concert by Swift scheduled to take place at their home stadium on Oct. 13 to Sept. 9 in anticipation of a potential playoff run in October. 

This didn't sit well with superstitious baseball fans, who viewed it as a possible jinx, akin to an announcer anticipating a no-hitter before the final batter is out. 

The rest of the summer went very well for the Astros, who took over the top spot in the American League West division.

And then Taylor Swift came to town. 

"Houston has turned in a lacklustre 7-11 record since her concert — including losing seven of the eight games immediately after," wrote D'Arcy Maine at ESPNW. 

Now, instead of taking the division title, the Astros are fighting it out for a wildcard spot with the L.A. Angels. 

While baseball fans are stereotyped as superstitious, some felt that blaming a pop-star curse for teams' terrible late-season runs was laughable. 

But both the Toronto Star and the Toronto Sun are now fretting that Swift's weekend concerts could spell doom for the Jays and their first post-season run since the World Series glory days of 1993. 

Some Jays fans are worried, too. 

Others, though, are confident in the curse-busting powers of the Blue Jays, which play their first post-Swift game on Oct. 8.
