The Mariners used first-pitch swinging to get to Zack Greinke Friday night:

“Historically, how he has pitched against us, you just don’t want to get deep in the count against him,” Mariners manager Don Wakamatsu said. “We had a plan right away to go jump on him as much as we could.”

Of the 34 hitters Grienke faced, 15 swung at his first pitch, five for hits. That included Langerhans’ third-inning home run to deep center field.

“He made some mistakes with that first pitch,” Langerhans said. “We were aggressive and didn’t miss them. That was a big key. Instead of fouling them off, we were putting them in play.”

That was the first earned run allowed by Grienke against the Mariners in 37 innings, since April 14, 2008. That streak included a one-hit, 3-0 victory last Aug. 30, an impressive win on the way to the Cy Young Award.

The Mariners adjusted and Zack could not adjust back fast enough. Minnesota hit him up for eight runs two starts ago. If Greinke many need to work on changing his patterns. Given his mental history, Zack’s frustration with the team might be hurting him as well. The Mariners won 7-1.
