Trevor Rosenthal Is Off To 1 Of The Worst Pitching Starts In MLB History

In 2016, Trevor Rosenthal was one of the best relievers in all of baseball. The St. Louis Cardinals closer had 48 saves with a 2.10 ERA and a 2.6 WAR.

In 2019, Trevor Rosenthal is one of the worst pitchers in the history of baseball.

It's early, of course, as the Washington Nationals - the team Rosenthal signed with after missing all of 2018 with Tommy John surgery - are only in their eighth game of the year.

Still, Rosenthal has been an absolute nightmare out of the bullpen for the NL East contenders.

Rosenthal has made four appearances out of the bullpen. He has faced nine batters. He's retired none of them. And his ERA is infinity.

The Nationals reliever's outing today was perhaps his most concerning. Rosenthal entered in the bottom of the eighth inning with Washington leading the New York Mets, 12-6. He plunked the first hitter he faced. He then threw multiple balls to the backstop and walked his second hitter. Washington's manager, Dave Martinez, hooked him after that. It was tough to watch.

It's unclear what the next move is for Rosenthal and the Nationals (whose bullpen as a whole has been a disaster).

Washington is attempting to contend for a playoff spot in a loaded division and the Nats can't afford to continue to put Rosenthal on the mound.

Perhaps a trip to the 10-day IL and a rehab stint in the minors could help.
