Josh Fields’ postseason debut was the clearest example yet for the Astros of how inexperience can affect this postseason negatively for the Astros. What followed Thursday in Kansas City when he settled down spoke to how important it is the Astros receive good outings from relievers other than the back-end trio of Tony Sipp, Will Harris and Luke Gregerson.
Fields, 30, averages 95 mph on his fastball. He threw three straight heaters for balls to finish off a four-pitch walk to Sal Perez — the last one nearly hit him — when Fields came in with the bases loaded in the sixth inning in Game 2 of the American League Division Series.
