PHOENIX -- Shohei Ohtani matched his career high with his 54th home run, Freddie Freeman went deep twice and the Los Angeles Dodgers clinched their 12th NL West title in 13 years by beating the Arizona Diamondbacks 8-0 Thursday. Ohtani's homer splashed into Chase Field's swimming pool behind the right-center wall for a 6-0 lead in the fourth inning. The two-run shot gave him 101 RBI for the season and matched his career-best home run total with the World Series champion Dodgers last year.
