SAN DIEGO — Thirteen months ago, Rockies lefty Austin Gomber was lost. He had an 0-4 record and a 12.12 ERA. He made an emotional admission, saying that being the centerpiece of the 2021 trade that sent Nolan Arenado to St. Louis had gotten into his head. That Gomber is long gone. On Wednesday afternoon at Petco Park, he blanked the Padres for six innings as the Rockies rolled to an 8-0 victory, their seventh consecutive win.
