Trevor Rosenthal, Nationals reliever, still has ERA of infinity

April 3, 2019

Trevor Rosenthal epitomizes the Washington Nationals’ bullpen woes so far this year.

Rosenthal made his third appearance of 2019 Wednesday against the Philadelphia Phillies and once again failed to get a single batter out.

Thus, his ERA of infinity stayed intact. Seriously.

As most baseball fans know, innings pitched are measured by how many outs a pitcher gets. When that number is zero, the stat is technically 0.0 innings. And when the earned run average calculation tries to divide a number of earned runs over zero innings, it can’t spit out a real answer.

Rosenthal helped blow a Washington lead Wednesday by walking Maikel Franco and pinch-hitter Scott Kingery. He was pulled from the game in favor of Kyle Barraclough, but the runners he left on base came home to score on a deep Andrew McCutchen double.

In his season debut, March 30 against the Mets, Rosenthal faced four batters, allowing three hits and a walk. He threw exactly one pitch the next day, and Amed Rosario slapped it for an RBI single (and later scored himself).

That’s seven batters combining for four hits, three walks and seven earned runs for Rosenthal. Instead of a toweringly high number, sites like baseball-reference.com have to list the righty’s ERA as “inf.”

According to ESPN Stats and Info, Rosenthal is the first pitcher ever to allow a run while not getting a single out in four consecutive starts. His streak dates back to Aug. 2017, the last time he pitched in a competitive game before this year, while with the St. Louis Cardinals.

Trevor Rosenthal just can’t buy an out.@EliasSports tells us that Rosenthal is the first P in MLB history to allow at least one run without recording any outs in four straight appearances.He’s faced 9 batters in that span.

Rosenthal, 28, has plenty of time turn his season around, but don’t feel bad in gawking at his infinitely awful start.
