SEATTLE - Hisashi Iwakuma scattered four hits over eight innings and Corey Hart hit an RBI single to lift the Seattle Mariners over the Kansas City Royals 1-0 on Thursday night.
Seattle won for the 11th time in 14 games since losing eight straight from April 15-22.
Iwakuma (2-0) was making his second start after beginning the season on the disabled list with a strained tendon on the middle finger of his pitching hand. The All-Star right-hander struck out seven and walked none.
Fernando Rodney worked around a pair of walks in the ninth to earn his 10th save in 11 chances.
Danny Duffy (1-3) gave up one run and two hits in six-plus innings. He has allowed two hits and a run in each of his first two starts this season after pitching out of the bullpen to begin the year.
