The Mets hadnt officially listed who their starting pitcher would be for the second game of their series against the Nationals until this afternoon, but its official now: David Peterson is getting the start. The 30-year-old lefty had lost his rotation spot after a string of very bad outings, but hes fared better working multiple innings in relief over his last couple of appearances.In four starts before moving into the bullpen/bulk role, Peterson had a rather unsightly 6.41 ERA with a 3.33 FIP that suggested he deserved better results and a 5.01 xERA that suggested slightly less ugly results. In those two appearances out of the bullpen after the Mets used Tobias Myers as an opener, Peterson threw a total of 7.0 innings with a 1.29 ERA, a 4.99 FIP, and a 4.07 xERA. With Kodai Senga having gone on the injured list this afternoon and Christian Scott having been called back up following a poor outing in his first major league start in two years, Peterson will clearly get a shot at sticking in the rotation. In the short term, at least, they dont have a ton of options, and Peterson and Scott will presumably serve in a five-man rotation alongside Nolan McLean, Clay Holmes, and Freddy Peralta.
