In Saturday's 4:15 p.m. PT game, Walker Buehler gets his first Coors Field start against German Marquez and the Rockies. Buehler has thrust himself into the Rookie of the Year conversation with his velocity, command and consistency. He showed all of that in seven innings vs. the Rockies at home two weeks ago, allowing only a solo homer to Gerardo Parra with six strikeouts.
