Hisashi Iwakuma extended his scoreless innings streak on the road to 25 and Justin Smoak homered off Justin Verlander to help Seattle Mariners beat the Detroit Tigers 8-0 on Wednesday night.
Iwakuma (13-6) matched his career high going eight innings, giving up just four hits and one unintentional walk. His 25-inning scoreless streak on the road matches a franchise record.
Verlander (13-11) allowed three runs, four hits, walked three and struck out six over seven innings. He was hoping to win consecutive starts for the first time in more than three months.
The AL Central-leading Tigers had won three straight and six of seven to close in on their third straight division title. Seattle had lost eight of nine.
