The Nationals non-tendered Peralta at the beginning of the month, worried he would cash in through arbitration or want a multi-year deal. But I find it hard to believe the Nationals wouldn't have re-signed the right-hander for $900,000. Of course, they do have a number of young relief options making less than that, so there's an argument to be made in principle for not spending money on relievers who can be easily replaced. All that, said, though, the Nationals are in the market for a veteran reliever who can possibly pitch in the ninth inning, and Peralta could have filled that role.
At any rate, the 34-year-old is apparently headed to Tampa now.
