As the Mets have closed within one game of .500 and put themselves back on the brink of contention for a Wild Card spot in the National League, their starting rotation deserves a ton of credit for their turnaround. As a group, the starters have a 2.59 ERA and 2.64 FIP in 128.1 innings over the span of 21 starts, which is basically two-thirds of a normal Jacob deGrom season.
That 2.59 ERA is the best in baseball since the All-Star break. So is the 2.64 FIP. And the 128.1 innings pitched by Mets starters rank third, though the only two teams ahead of them in that category have had two and three more starts, respectively.
