When the top of the fourth ended, the Royals had a 3-1 lead.

Mariners starting pitcher Luis Castillo's chance at his first quality start since March 30 against the New York Yankees ended in the top of the sixth.

Collins hit an RBI double to score Caglianone to give Kansas City a 4-1 lead, the eventual final.

Castillo finished his day with five strikeouts, two walks, one hit batter and four earned runs allowed on six hits in six innings pitched.

It was the three-time All-Star's first time pitching through the sixth inning since his outing against the Yankees.

"I think throughout my whole career, you go through some bad stretches," Castillo said after the game via translator Freddy Llanos on Sunday. "And I've said it before, I've said it in several interviews, you go through these bad stretches and they're not going to last forever. So, just continue working. Same mentality whether you're going through a good stretch or bad stretch."

After the Royals bolstered their advantage to 4-1, Seattle was unable to get further into the lineup than the minimum in the sixth, seventh and ninth innings. Rodriguez was left stranded at first in the eighth.

Kansas City's starter, Kris Bubic, fanned seven, walked two and allowed one earned run on four hits in seven innings pitched.

"For whatever reason, we haven't seen the ball super well against lefties," Wilson said. "We've got to make some adjustments offensively and get back to doing what we do in terms of getting guys on-base and pushing the envelope that way. And once we do that, whether it's a righty or lefty out there, I think we'll be in good shape."

The Mariners will look to bounce back against one of the best teams in the National League, the Atlanta Braves, in the first of a three-game series at 6:40 p.m. PT on Monday at T-Mobile Park in Seattle.

JR Ritchie will start for Seattle and JR Ritchie will get the nod for Atlanta.
