Jim Leyland wore a small smile last week as he talked about team chemistry. He said if you win, you've got a great clubhouse, but if you lose, then it's said you have a bad clubhouse.

He's right, of course. Almost everything else follows success and failure, and there are some situations in baseball this season -- let's call them the Tinderbox Ten -- that could be inflamed this year, depending on how events play out.

Here are the 10 most inflammatory situations in baseball in 2013:

1. Charlie Manuel's status with the Philadelphia Phillies
Manuel made it clear recently that he'd like to continue managing beyond 2013. But his contract is set to expire this fall, and general manager Ruben Amaro isn't ready to commit beyond this season. From The Associated Press:

    "We'll see what happens at the end of the year and go from there," Amaro said.

    Manuel isn't one to make demands, but it seems he's a bit peeved.

    "I'm not disappointed in it at all. I don't know if I get it or not," Manuel said. "I think they can do whatever they want to do. That's how I look at it. Actually, when you get right down to it, it doesn't bother me a whole lot because I have nothing to do with it. If you stop and think about it, I don't have nothing to do with it. I mean that in a good way."

On top of that, there is a perception that Manuel's heir apparent -- Ryne Sandberg -- is already on the big league coaching staff, something Amaro has flatly denied.
