This week, Dallas Keuchel mentioned two particular joys of his job as a Houston Astros starting pitcher. One is when he takes the mound for the first inning, his nerves cresting within him. He likes to take one deep breath and soak in the stadium's atmosphere. The other is when he warms up in the opposing bullpen and hears alcohol-tinged heckling. Depending on the city, a collection of fans and accompanying concessions might have already materialized, funnel-cake fragrance coursing through the air.
