Edwin Diaz was already used earlier in the game so when the Mets took the lead in the ninth the team was scrambling for a closer. Peterson, having not pitched in the series to this point, stepped up and closed the door on the Brewers by inducing a Brice Turang double play. Peterson figures to start in the NLDS against the Phillies, though the Mets have a bevy of rotation options.
Frelick will get the nod even after being diagnosed with a bone bruise in his left hip Friday. The 24-year-old will be closely monitored according to Brewers manager Pat Murphy, but all signs point to him being an option for Milwaukee as long as they're still in the postseason. The full lineup for the Brewers against Luis Severino and the Mets: Brice Turang 2B, Jackson Chourio LF, William Contreras C, Garrett Mitchell CF, Willy Adames SS, Jake Bauers DH, Rhys Hoskins 1B, Frelick RF and Joey Ortiz at third base.
