Milton Bradley says he's not bothered by having to compete for a starting job. A couple more days like Tuesday and it won't be much of a contest.
"He's really working hard, he just needs to stay patient and let the game come to him," Mariners manager Eric Wedge said. "I think he's having a good time. He's enjoying himself, he's enjoying his teammates, I love his work ethic. Just want to see him sustain that."
Michael Saunders, whom the team has given previous chances to take over the position, is Bradley's main competition in left field.
Adam Kennedy and catcher prospect Steven Baron hit solo home runs for Seattle.
The Rangers scored two runs in the third inning on an RBI groundout by David Murphy and two-out double by Brian Barden, then got two more in the ninth on a two-run single from Chris Davis.
Matt Harrison pitched two innings for the Rangers and gave up Kennedy's homer.
"I kind of made a bad decision going in (with the count) 3-1, and he turned on it," Harrison said.
Nate Robertson, trying to win a spot in the Mariners' rotation, gave up three hits and struck out three in two innings.
Notes: Rangers C Yorvit Torrealba was a late scratch from the Texas lineup due to lower back stiffness. ... Rangers RHP Brandon Webb, a former Cy Young Award winner who has dealt with injuries the past two years, threw a 15-minute bullpen session Tuesday morning and got through it with no problems. "We'll just keep running him out there until that arm strength comes back the way it should come back," Rangers manager Ron Washington said. ... Mariners CF Franklin Gutierrez, who'd been dealing with stomach problems, made his Mariners spring training debut and went 1 for 3.
