Los Angeles Dodgers starter Yoshinobu Yamamoto was named an MLB All-Star for the first time on Sunday. On Monday, he posted his worst outing of the season. The Milwaukee Brewers chased Yamamoto two outs into his start while tagging him with five runs — three of them earned — during an entire run through the order.

Andrew Vaughn hit a three-run homer in his first plate appearance with his new team, Freddy Peralta threw six shutout innings and the Milwaukee Brewers trounced the Los Angeles Dodgers 9-1.

Yoshinobu Yamamoto surrendered five runs in the first inning and posted the worst performance of his MLB career during a loss to the Brewers Monday.
