Drew Pomeranz elevates himself to Sox’ clear No. 2 starter

August 13, 2017 GMT

Heading into spring training, Drew Pomeranz (above) was in a battle with Steven Wright to win the Red Sox’ fifth starter job. Six months later, he’s elevated himself to the Red Sox’ clear No. 2 behind ace Chris Sale. Since May 20, the Red Sox are 21-8 when either Sale or Pomeranz is on the mound — and in that span Pomeranz has logged an even lower ERA than his Cy Young Award frontrunner teammate.

Here’s a look at the five best American League pitchers over that span, ranked by ERA (all statistics as of the start of play on Thursday):

1. Corey Kluber, Indians

95 1/3 IP 1.70 ERA 142 strikeouts .472 OPS against 

2. Luis Severino, Yankees
