Mookie Betts hit a three-run homer, Cody Bellinger added a two-run double and the Los Angeles Dodgers beat the Arizona Diamondbacks 6-0 on Monday night behind Tyler Anderson, becoming the first major league team to clinch a playoff spot this season. The Dodgers thought they had secured a playoff berth Sunday after beating the Padres, celebrating with a postgame toast and distributing caps with the postseason logo on them.
