Ty Blach had a 4.56 ERA in his Giants career, but the record books at Oracle Park will always show that he was the organization's Opening Day starter in 2018. Blach filled in against the Dodgers when Madison Bumgarner got hit by a line drive in his final appearance of the spring, but in every other season since 2014, Bumgarner threw the first pitch.
That'll change in 2020. Bumgarner should take the ball on March 26 and kick off the Diamondbacks' season against the Braves. The Giants might turn to Jeff Samardzija, who had a strong 2019, or Johnny Cueto, their current ace if he's fully healthy.
