Zack Greinke might be taking a new role this postseason for the Astros. Houston manager Dusty Baker said there's a "distinct possibility" that Greinke pitches out of the bullpen during the postseason. Greinke missed time this month after testing positive for COVID-19, then was placed on the injured list with neck soreness. He hasn't made a relief appearance since 2007 and has started every postseason game he's pitched in over his 18-year career. The Astros are expecting to roll with Lance McCullers Jr, Framber Valdez, Luis Garcia and José Urquidy for their postseason rotation.
