Lefty Drew Pomeranz is also on the roster, giving the A's two true long men in their bullpen for the affair. They'll be joined by closer Sean Doolittle, right-handers Luke Gregerson, Dan Otero and Ryan Cook, and left-hander Fernando Abad. Fellow southpaw Eric O'Flaherty is not on the roster because of a reported arm injury.
Starters Sonny Gray, Jeff Samardzija and Scott Kazmir, all of whom pitched over the weekend, were left off the list, because clubs can alter rosters for a potential AL Division Series.
With just eight roster spots allotted to pitchers, the A's have a deep bench on hand for the crucial game, featuring a slew of right-handed batters not expected to be in the starting lineup against Kansas City ace James Shields, including Derek Norris, Jonny Gomes and Nate Freiman. Oakland can also counter with switch-hitters Nick Punto and Alberto Callaspo.
Speed is there in pinch-run options Billy Burns and Sam Fuld, and so is infielder Andy Parrino, who provides excellent defense as a backup option to starting shortstop Jed Lowrie.
