With the sky falling on the 49ers' season after two bad defeats, everyone is looking for someone to blame, with coach Jim Tomsula and quarterback Colin Kaepernick getting most of it.

Well, never mind them. We suggest Taylor Swift. That's right, the pop star who played two concerts at Levi's Stadium in mid-August.

Swift has become a baseball jinx, according to an ESPNW story. She played at the home of the Washington Nationals in July, and the team is 33-39 since then. The Houston Astros are 8-11 -- and in danger of falling out of playoff contention -- since she visited Minute Maid Park in September. The San Diego Padres are well under .500 since her performance at Petco Park in August, but they're lousy anyway, so maybe that shouldn't count.

In fairness to Swift, expectations for the 49ers aren't very high this season. And the singer did play two concerts at Gillette Stadium shortly before she visited Levi's. The Patriots are 3-0.
