Hyun-Jin Ryu hit a home run and pitched seven solid innings, Cody Bellinger hit a grand slam and the Los Angeles Dodgers reached the 100-win mark Sunday with a 7-4 victory over the Colorado Rockies. With the Dodgers still undecided on a starter for the NL Division Series opener Oct. 3, Ryu (13-5) made his case by giving up three runs and six hits over seven innings with no walks and eight strikeouts. Four batters after Ryu's shot, Bellinger hit his fifth career grand slam and second this season, going deep off left-hander Jake McGee as the Dodgers improved to 100-56 and reduced their magic number for clinching the best record in the NL to one.
