Six of the first seven Mariners reached with a hit to start the second, and all six scored. Kyle Seager opened with a double off the right-center wall. Justin Smoak then singled to right.
With one out, Mike Zunino singled to left to score Seager, Dustin Ackley sent Smoak home with a single to right, Brad Miller's double drove in Zunino, and Franklin hit his eighth homer of the season on 0-2 pitch. The six runs were the most the Twins have allowed in one inning.
The Twins loaded the bases with one out on two singles and an error in the third but Trevor Plouffe struck out, and Clete Thomas bounced out to second.
