SEATTLE -- After spending the past decade as one of baseball's most consistent shortstops, repeated injuries aren't easy for Jack Wilson to deal with.

Wilson found himself on the 15-day disabled list after feeling a strain behind his right knee on May 5 against the Rays, and he pulled his right hamstring during an at-bat with Double-A West Tennessee on a rehab assignment May 15, leaving his return further in doubt.

"There's nothing I can do to stay positive right now, absolutely nothing," he said. "I have my family here, and that's nice, but there's nothing you can do. You can't help your team. Being here is tough because you want to cheer them on, but at the same time you can't really do anything."

Manager Don Wakamatsu said there's no timetable for Wilson's recovery, and he'll likely need another rehab start before coming back. Entering this year, Wilson had logged the sixth-highest total of games among shortstops since 2001, but bouts with injury caused him to miss 131 games in the 2008 and 2009 seasons.

That has left Wilson feeling in the dumps, and said in a matter-of-fact manner Saturday that his career may be nearing its end.

"This is when you actually look at your career and if it's going to last too much longer," he said. "In reality, there's nothing more that I can do. If it ends up pulling, there's nothing you can do about it. You're out two weeks every time you do it."

Wilson said he's on a regular treatment schedule with team trainers and doing lots of stretching, resting and icing to try to get healthy. But he has come to terms with the fact that his hamstrings aren't what they used to be.

"Anyone who's on the DL, and who has been on the DL as much as I have since I've been over here, is going to feel like absolute crap," he said. "You spend most of your career on the field, and ever since I've been here, I've played a quarter of the games, maybe a fifth. That's not really my style."

Sweeney's back isn't 100 percent yet

SEATTLE -- You wouldn't know it from his performance Friday night, but Mike Sweeney's back still isn't 100 percent.

Sweeney went off for two home runs and six RBIs in the Mariners' 15-8 romp over the Padres, but manager Don Wakamatsu said his designated hitter felt some stiffness in his lower back afterward.

The injury has left Sweeney as a day-to-day player. Wakamatsu said Sweeney felt fine Saturday, but he'll likely get the day off Sunday in lieu of Ken Griffey Jr., and with Seattle's next three games against right-handed starters, he could have plenty of time to get healthy.

That is, unless he keeps up his torrid pace at the plate and forces Wakamatsu to play him against righties. Sweeney ranks sixth in the Majors in at-bats per homer (11.6).

"He came to Spring Training in tremendous shape, lighter than I've ever seen him," Wakamatsu said. "Last year, if you look at his numbers from the time he got to play more consistently, they were great. He had a great Spring Training and didn't get as many at-bats as we'd like early, but since he's gotten consistent at-bats, the power has even come back. That's a nice thing to see."

Moore's injuries are healing quickly

SEATTLE -- A rare bit of good news on the injury front is that Mariners catcher Adam Moore's bruised left heel and jammed left knee are healing quickly. But that will mean a tough decision for manager Don Wakamatsu.

Moore was placed on the 15-day disabled list on May 16. He was injured a day after his best day at the plate, a 2-for-4 outing at Tampa Bay, where he had a double and home run.

His replacement, Josh Bard, has hit .400 with five runs and four RBIs in five games to supplant regular starter Rob Johnson in the lineup, and Wakamatsu will have to choose two of the three when Moore comes back.

Wakamatsu expects Moore to be healthy enough to catch pitcher Erik Bedard in a bullpen session next Saturday.

Worth noting

On Friday, Cliff Lee became the first pitcher in Mariners history to earn a win despite allowing eight runs. ... The Mariners have posted a record of .500 or better in each of the last 10 seasons of Interleague Play, going 107-74 in that span for a .591 winning percentage.
