Blanton, making his second spot for an injury-riddled Royals rotation, was lights-out against the Mariners. He faced one over the minimum through six innings -- a Robinson Cano homer -- before parting after giving up a hit to lead off the seventh.
Blanton registered the win, his second straight, while walking none and striking out seven.
"It's been fun," Blanton said of his return to the game. "It's a good group of guys to hang out with. They like to have fun so it has made the whole experience enjoyable."
As for his effort Monday, Blanton wasn't necessarily in awe of himself.
"I felt OK," he said. "Salvy [Perez] did a great job behind the plate. I dodged a couple bullets early with deep fly balls. Settled in after that. And we did a great job offensively."
