Left hander Drew Pomeranz is a decent example of a failed starting pitcher that retransformed himself into what looks like a solid reliever out of the bullpen. The Tennessee native has appeared in 242 games throughout his career, however 140 of which were starts.
Pomeranz signed a one-year deal with the San Francisco Giants heading into the 2019 season however also began to garner a decent amount of interest during the trading deadline in July. He would eventually be traded to the Milwaukee Brewers with Ray Black for Mauricio Dubon on the 31st of July.
While pitching with the Brewers, Pomeranz appeared in 25 games as he tossed 26.1 innings with a 2.39 ERA while also striking out an impressive 45 batters. A big difference from his time with the Giants as he owned 5.68 ERA in 77.2 pitched, however 17 of his 21 games pitched in came as starts. Overall out of the bullpen, Pomeranz pitched to a 1.88 ERA while with both the Giants and Brewers during the 2019 season.
At the age of 26 in 2015 with the Oakland Athletics, Pomeranz pitched in 53 games and only made 9 starts during that campaign. He would pitch to a 3.66 ERA while striking out 82 batters in 86.0 innings pitched.
So while Pomeranz has a career ERA of 4.04, I imagine that his ERA is substantially lower out of the pen and is someone the Mets might want to consider. With the likely departure of Luis Avilan and the need to upgrade, Pomeranz makes sense and very well maybe a perfect fit.
