The MLB free-agent market is running thin, which means you can count on teams to make a few desperation offers to fill out their rosters. While there are still valuable players to be had, there are also some guys who simply aren’t worth the risk.

In this list of the 10 biggest land mines left in free agency, the rankings are based on risk versus reward—in other words, which decisions have the greatest potential to blow up in a team’s face while also creating the largest explosion?

Reliever Brian Wilson, for example, is only at No. 7 because the Dodgers are paying his 2015 salary and he can be signed at the league minimum. Cuban infielder Yoan Moncada, on the other hand, is near the top of the list because of the huge investment required to sign him.

After reading these names, just don’t say I didn’t warn you.
