Mariners 2, Twins 0: Mike Zunino and Michael Saunders homered while Hisashi Iwakuma struck out a season-high 10 in seven innings as host Seattle blanked Minnesota in the opener of a four-game series.

Twins starter Kevin Correia made two mistakes on 3-2 pitches with Zunino clubbing one over the wall in left in the second inning and later allowing Saunders’ two-out blast to center in the seventh. Correia (4-11) allowed two runs and five hits over seven innings as the Twins lost for the 11th time in 14 games.

Iwakuma (7-4) continued his mastery of Minnesota by allowing four hits and walking none in a 105-pitch effort as the Mariners won for the sixth time in eight games. The right-hander is 5-0 in five all-time outings against the Twins and hasn’t allowed an earned run while giving up 20 hits in 33 2/3 innings.

Danny Farquhar struck out two in the eighth and Fernando Rodney fanned two in a perfect ninth to raise his American League-best save count to 26. Rodney has converted 15 consecutive save opportunities dating back to a blown one against Tampa Bay on May 13.

Minnesota threatened in the seventh when slow-footed Kendrys Morales led off the inning with a single but was unable to score on Oswaldo Arcia’s double into the right-center field gap. Iwakuma escaped damage by inducing Chris Colabello to bounce to third and striking out Sam Fuld before the bullpen took over.
