The Mets will slot Logan Verrett into the rotation for a spot start on Saturday in Milwaukee. The Mets and Pirates were rained out last night and are playing a doubleheader today. The Mets also don't have an off day after this series, as they're set to play four games in Milwaukee beginning on Thursday night.
With that, the team needs an extra starting pitcher before the rotation comes back around to either Steven Matz, who pitched the first game of the doubleheader, or Jacob deGrom, who is set to pitch the second game. Without the extra starter, one of those two would need to pitch on short rest in Milwaukee.
In 36.1 innings this year, Verrett has a 3.22 ERA and 4.01 FIP. He's made three starts already, and he has a 4.30 ERA in them, though a small sample split like that shouldn't be given too much weight. The soon-to-be 26-year-old made four starts for the Mets last season, too, and in seven career starts, he has a 3.89 ERA.
