With plenty of free-agent relievers remaining on the board, the Washington Nationals have reportedly made one available via trade.

Projected to earn $8-9 million in his final year of arbitration before free agency, the Nationals are "likely" to move Tyler Clippard, a source tells Ken Rosenthal of FOX Sports.

Rosenthal notes that an abundance of right-handed options in the bullpen has made the 29-year-old expendable.

Clippard, who's coming off his second All-Star season, has been exceptional in his seven seasons in Washington, posting a 2.68 ERA and 1.04 WHIP in 414 appearances. In 75 games in 2014, Clippard fashioned a 2.18 ERA, 0.99 WHIP and 82 strikeouts in 70 1/3 innings.
