Nathan has a clause in his deal with the Nationals that allows him to opt out Friday, Chelsea Janes of the Washington Post reports.

EDGE Analysis

He pitched on back-to-back days for the first time this spring Wednesday and Thursday, and while the 42-year-old hasn't looked bad so far (8:3 K:BB in 10.2 innings), the Nats already seemingly have seven relievers locked into spots after the late signing of Joe Blanton. If Nathan does opt out, he may have done enough to earn a look from another team in need of some veteran savvy in the middle innings.
