Seattle Mariners starting pitcher Hisashi Iwakuma retired the first nine batters he faced, and turned in a solid 4.0-inning start, but it was not enough in a 4-2 loss against the Kansas City Royals Wednesday afternoon in Cactus League play at Surprise Stadium.

After opening spring play with a 10-4 record, the Mariners (11-7) have dropped six of their last seven games, including a current five-game losing streak.

Iwakuma retired the first nine batters he faced, before allowing a pair of runs in his final inning of work. The right-hander allowed four hits, two runs and struck out one in the longest outing by a Mariners starter this spring. Reliever Tom Wilhelmsen (0-1) recorded the loss allowing one run in his only inning of work. Left-hander Danny Hultzen(1.0 IP, 1 H) and Stephen Pryor (1.0 IP, 3 K) turned in scoreless relief efforts.

The Mariners were out-hit 9-4 by the Royals, with Kyle Seager going 2-for-4 with one RBI. Second baseman Carlos Triunfel plated the Mariners first run with a solo home run, his first of the spring.

Royals starting pitcher Ervin Santana did not factor in the decision, allowing one run and striking out seven in 4.0 innings. Right-hander Nathan Adcock (1-0) recorded the win allowing one run in 1.0 inning of work and Aaron Crow recorded his first save with a 1-2-3 ninth inning. With the win the Royals improved to 14-2-1 this spring.
