Greinke is expected to start Game 4 of the World Series in Atlanta on Saturday, Marly Rivera of ESPN.com reports.
Greinke has been a starter for the vast majority of his 18-year career, but he suffered a neck injury in late September and closed the year in the bullpen. He's made two appearances in the postseason, one of which was technically a start, but those outings lasted a combined 2.1 innings. It's unlikely he'll be able to pitch particularly deep in Game 4, as the last time he reached even three innings in an appearance came back on Sept. 19.
