Why Yoshinobu Yamamotos one-run brilliance only leads to more frustration for Dodgers ace

SAN DIEGO – Yoshinobu Yamamoto was upset.You could see it in his face.You could hear it in his voice.In his mind, he was responsible for the Dodgers’ 1-0 loss to the San Diego Padres on Monday night at PetCo Park.Never mind that he pitched seven innings.Never mind that he struck out eight batters.Never mind that he held the Padres to three hits.One of the hits was a first-inning home run by Miguel Andujar, and Yamamoto said in Japanese, “It decided the game.”Yamamoto sounded almost exasperated with himself.He was aware of the circumstances.

Yamamoto said he intended for the pitch to be lower.“It was a...
