Madison Bumgarner starts for the Giants, and manager Bruce Bochy has 10 bullpen options: right-handers Santiago Casilla, Johnny Cueto, George Kontos, Derek Law, Sergio Romo, Jeff Samardzija and Hunter Strickland, and left-handers Javier Lopez, Steven Okert and Will Smith.
Cueto and Samardzija are usually starters.
Nunez hasn't played since Sept. 25 because of a strained right hamstring.
New York went with an eight-man bullpen behind starter Noah Syndergaard: right-handers Bartolo Colon, Jeurys Familia, Robert Gsellman, Addison Reed, Hansel Robles and Fernando Salas, and left-handers Jerry Blevins and Josh Edgin. Colon, a starter, excelled in a bullpen role during the 2015 postseason.
