Minnesota rookie starter Kyle Gibson had trouble again against the Mariners as the Twins dropped the finale of their three-game series against Seattle, 6-4, on Sunday afternoon at Safeco Field.

Gibson served up home runs to Michael Saunders and Nick Franklin in the fourth inning. The young right-hander was tagged for five runs on seven hits and one walk while striking out three over five innings pitched for his third loss of the season.

Gibson allowed nine earned runs combined over his last three starts. He is scheduled to make his next start Saturday at home against the Astros.
