SCOTTSDALE, Ariz. -- Seattle received three shutout innings from right-hander Hisashi Iwakuma as the Mariners extended their Cactus League winning streak to three games with Friday's 5-4 victory over the San Francisco Giants.
In five innings spanning two outings, Iwakuma, Seattle's No. 2 starter behind Felix Hernandez, has allowed one hit and walked one batter -- both in Friday's game.
"My fastball was pretty sharp," Iwakuma said through translator Antony Suzuki. "I was able to command, like I did last time, and I felt I was able to throw a little harder today. So overall it felt good. I'm pleased with where I'm at right now."
The Mariners scored twice in the third inning with two outs. Franklin Gutierrez doubled home a run on a drive to right-center field that Gorkys Hernandez nearly caught with a sliding attempt on the warning track. Stefen Romero's single scored Gutierrez.
Pence narrowed the difference to a single run by depositing Joel Peralta's 3-1 pitch over the lawn-seating area in left field, following Buster Posey's double to deep right-center field. The Mariners got those two runs back in the eighth thanks to Chris Taylor's RBI double and Tyler O'Neill's RBI single, then the Giants countered with a pair in the bottom of the ninth off Tony Zych.
Samardzija, making his third start of the spring, allowed three runs on six hits and a walk while striking out one in four innings.
