Seattle Joel Pineiro, making his third major league start, pitched one-hit ball for six innings as the Seattle Mariners avoided getting swept for the first time this season with a 4-0 victory over the Kansas City Royals on Thursday night.
The Mariners (73-29) still have not lost three straight all year.
Seattle relievers Jeff Nelson, Arthur Rhodes and Kazuhiro Sasaki each worked one inning to complete the two-hitter. It was Seattle's eighth shutout of the season, while Kansas City was blanked for the fifth time.
Pineiro (1-0) allowed Brent Mayne's two-out single in the third. He walked none and struck out six before being taken out at the start of the seventh after throwing 78 pitches.
Mayne singled off Sasaki in the ninth for Kansas City's only other hit.
Pineiro, whose name has been mentioned in trade speculation with Toronto involving Blue Jays outfielder Jose Cruz Jr., has allowed one earned run in 171/3 innings in five appearances for Seattle this season, an 0.52 ERA.
The 22-year-old Pineiro outpitched left-hander Chris George, called up Wednesday night from Triple-A Omaha to take Dan Reichert's place in the Royals' rotation.
Reichert was sent down to Omaha.
In his major league debut, George (0-1) didn't give up a hit until Ichiro Suzuki's infield single in the third.
The Mariners scored their first run in the fourth when Bret Boone and John Olerud opened with doubles off George. They made it 2-0 in the fifth when Stan Javier singled, stole second, went to third on an infield out and Carlos Guillen tripled.
George was relieved by Blake Stein after Mike Cameron doubled leading off the sixth. Cameron went to third on David Bell's infield single, and Dan Wilson singled Cameron home for a 3-0 Seattle lead.
Suzuki added an RBI single off Stein in the eighth.
George gave up three runs on six hits in five-plus innings. He walked two and struck out two.
