Two league sources have told ESPN's Jayson Stark that the Twins have an insurance policy on the contract of closer Joe Nathan.

The policy figures to reimburse Minnesota a "significant" chunk of the $11.25 million the closer is owed this season.

Receiving money back on Nathan's deal would allow the Twins to hunt a replacement closer without actually spending additional money.

One general manager said that he wouldn't be looking for simply a stop-gap if he were the Twins.

"In my experience, it takes 16 months to get right after Tommy John," he said. "Yeah, in a year he'll be throwing. And he should probably be pitching. But he might not be the same for 16 months. So if you're going to make a deal in July, you'd be better off with a guy like Heath Bell, because he can get you through two years if you need him to, and he can set up for a year if you need him to do that."
