Yamamoto gave up a grand slam to Gabriel Moreno and a solo home run to Ketel Marte in five innings in a 5-3 loss on a night when the Dodgers don’t get enough out of their hard contact.

The Los Angeles Dodgers took a loss as division play began on Thursday night. Facing off against the National League West rival Arizona Diamondbacks, the Dodgers fell 5-3 even though they had their best pitcher on the mound.

Despite having a lengthy injury layoff, Yoshinobu Yamamoto had a solid first season with the Los Angeles Dodgers last year. The Japanese pitcher played a vital role in anchoring their rotation in the postseason to help the Dodgers clinch the World Series title.
