SEATTLE -- An extended streak of success was only a matter of time, Texas Rangers players had been saying the past two months.
They were supremely confident, even when they were playing some of their worst games of the season, and weren't worried that the All-Star break would disrupt the start of something good.
It turns out those players knew what they were talking about.
Matt Harrison allowed one run in 72/3 innings, and Mitch Moreland launched an early three-run homer as the Rangers sank the Mariners 3-1 to complete a four-game sweep and extend their winning streak to 11 games.
Never miss a local story.
No team in baseball this season has won as many games in a row, and the Rangers' streak has helped them open a four-game lead over Los Angeles in the American League West.
The Angels lost three times this weekend at Oakland ahead of a three-game home series against the Rangers beginning Tuesday. Texas wants to keep building on the momentum that was built before the All-Star break and never disappeared at Safeco Field.
"When you know you've got a great team and a great group of guys, you're going to expect the best," shortstop Elvis Andrus said. "We're playing great baseball, and everything is going well for us."
Manager Ron Washington saw Thursday afternoon that his team hadn't lost its focus while he, the coaching staff and five players were with baseball's best in Phoenix.
The Rangers went through their early workout quickly and without any mistakes, which indicated to Washington that there wouldn't be a letdown to open the second half.
"We expected ourselves to come out and play well," he said.
Pitching has had plenty to do with that. The Rangers have allowed only two runs in the past five games, the best five-game run in club history.
Harrison (8-7) continued the rotation's dominating run. He walked the first Seattle hitter of the game, Ichiro Suzuki, but induced a double-play grounder to clean the slate.
The Mariners didn't have another base runner until Justin Smoak lined a one-out single up the middle in the fifth. Harrison recorded 12 ground-ball outs after learning during his pregame warm-up that his sinker would be a good pitch for him.
"I felt good with my sinker in the bullpen, so I threw a lot of those," said Harrison, who has a 1.94 ERA over his past 10 starts. "I was able to make that pitch time and time and time again today and make them put the ball on the ground."
Blake Beavan, the Rangers' first pick in the 2007 draft, pitched well after the second inning.
The Rangers just missed against him in the first, loading the bases with two outs before Nelson Cruz struck out. But David Murphy singled to start the second, and Mike Napoli walked.
Moreland followed and crushed a hanging curveball deep into the right-field seats. It was his first homer since a solo shot June 28 at Houston and his first RBIs after a 10-game drought.
"It was big for us because it was the difference in the ballgame," Washington said. "After that, it was pitching on both sides."
The only other blemish for Beavan (1-1) came on his final pitch, which struck Ian Kinsler in the helmet. He was stunned but stayed in the game and received an apology from Beavan on his way to the bench.
The Irving High product allowed three runs on six hits in 62/3 innings, but it wasn't enough against the hottest team in baseball.
"Mentally, we're still in the same place," Andrus said. "We just want the winning streak to keep going."
