Yu Darvish helped the Rangers defeat the Mariners 9-3 on Friday night, earning his 15th win and getting his 200th strikeout in the process.

Darvish struck out nine in seven innings. He complimented his mid-90s fastball with a breaking pitch about 30 mph slower.

"It's a tough pitch, something you're not used to," Seattle's Kyle Seager said. "It definitely throws your timing off a little bit. He located really well with it. When he threw them, he threw it with a purpose."

With 205 strikeouts, Darvish is the first Major League rookie over 200 since Daisuke Matsuzaka struck out 201 batters for Boston in 2007.
