Moyer pitched seven strong innings for his 12th victory in 20 career decisions against the Royals as the Mariners completed a three-game sweep with a 10-2 win Thursday.
"We've played eight games," he said. "It's something to work off of and build off of, but it's a long season."
With the win, Seattle already matched the number of road sweeps it had all last season while going 25-55 away from home. And the Mariners' team ERA is an impressive 3.33.
"We're excited," said Richie Sexson, who had an RBI double and a two-run homer. "This is a great series for us, a great way to start a road trip."
The Royals, who scored only five runs in the series, are getting consistent production only from Mike Sweeney.
Jeremy Reed had a three-run double in the six-run fourth for the Mariners, who hadn't swept in Kansas City since Sept. 6-8, 2002.
"We got good pitching and we got some big hits," manager Mike Hargrove said. "You combine all those, usually you come out on the good side."
Moyer (2-0) gave up nine hits and two runs, with four strikeouts and one walk. He gave up a run in each of the first two innings, and then retired John Buck on a fly ball for the third out with the bases loaded in the third.
After that, he cruised.
"I felt pretty good on the mound," Moyer said. "It was just a matter of locating some pretty good pitches."
The ball Sweeney hit for an RBI double in the first inning was not even in the strike zone, he said.
"He just went down and got it. There's nothing you can do but tip you hat to an at-bat like that."
Reed's three-run double keyed a six-run fourth inning against rookie right-hander Denny Bautista (1-1). Sexson had an RBI double in the fourth and a two-run home run off reliever Mike Wood in the sixth.
Bautista, making his seventh major league start, went 3 1/3 innings and was charged with six runs on four hits, three walks and a strikeout.
"It seemed like he didn't have any feel for his fastball today, so he went to his breaking ball," Royals manager Tony Pena said. "Sometimes you see pitchers changing like that, but not after only one inning. The first inning he's throwing 95, 96, 98 (mph) and it seemed like they didn't want any part of him. But then he just changed."
In the fourth, Wilson Valdez hit a two-run double, and Mike Wood relieved Bautista and walked Ichiro Suzuki intentionally to load the bases. Two pitches later, Reed's bases-clearing double sailed into left-center. Sexson then made it 8-2 with an RBI double.
Sweeney has hit in eight consecutive games and is batting .359 with four doubles and eight RBI.
