Oklahoma City roughed up Foster Griffin while denying Omaha a fifth straight victory.

The Dodgers scored six times in the second inning en route to a 12-3 win at Werner Park on Wednesday.

All 12 of their runs came off of Griffin (5-2), who suffered his first loss since April 13.

Cameron Perkins started the onslaught for Oklahoma City with a solo home run to open the second. By the end of that inning, 10 Dodgers had batted and six had scored. Connor Joe drove in two runs.

Creighton product Jake Peter added a two-run homer in the third inning, and Edwin Rios clubbed a three-run blast in the fourth. All three homers came off of Griffin, who had given up five previously.

The former first-round pick for Kansas City had posted five quality starts in his previous six outings. Griffin, in his first season at the Triple-A level, saw his ERA jump from 3.40 to 4.97.

Justin De Fratus (1-2) gave up solo homers to Jorge Bonifacio and Cheslor Cuthbert — both of which traveled more than 400 feet — but left after seven with a 10-run lead in his first win of the season.

Royals first baseman Lucas Duda was the designated hitter for Omaha for the second straight night, going 1 for 4 with a single in the second game of his rehabilitation assignment.

Bonifacio drove in the final run for the Chasers with a single in the eighth.
