SEATTLE -- The Mariners placed right-handed reliever Mark Lowe on the 15-day disabled list on Wednesday and recalled reliever Shawn Kelley from Triple-A Tacoma.
The 26-year-old Lowe, 1-3 with a 3.48 ERA in 11 relief appearances this season, has lower back disc inflammation, an ailment that has bothered him periodically since last November.
Lowe explained on Wednesday that the disc was putting pressure on a nerve that caused pain in his buttocks and the back of his right leg.
"It could be [healed] within seven days," Lowe said, "but we're going to play it safe. It's something I have been battling. I think after that bunt play [against the Rangers] where I slipped, I think the slide just fired it up.
"I finally went in and thought an MRI would probably be the best thing. So that's what we did."
Kelley, who started the season with the Mariners, was sent to the Minors last week to make room on the roster for left-handed starter Cliff Lee. He made two appearances with Tacoma, allowing two earned runs in 2 2/3 innings.
Wilson departs early with injury
SEATTLE -- Mariners shortstop Jack Wilson, who beat out a bunt for a one-out single in the third inning, was forced to leave the game at the end of the frame Wednesday night because of discomfort behind his right knee.
But he was encouraged by how much better it felt after the game.
"They are thinking it might be scar tissue from when I injured it in Spring Training," he said. "That would be really, really good news."
Wilson advanced to second base on an infield out and spent a couple of minutes after the inning trying to get his hamstring loose so he could remain in the game. But he came off the field and was replaced by Josh Wilson.
Jack Wilson said he initially thought he had pulled a muscle, but that was ruled out.
"When I first came out of the game, it was pretty sore," he said, "but after walking around, it feels a little bit better. Hopefully, I'll feel better tomorrow."
Wilson is hitting .253 with seven doubles and seven RBIs.
Griffey moving up all-time RBI list
SEATTLE -- It seems like each time he gets a hit or drives in a run, Ken Griffey Jr. moves up a notch on an all-time list.
The run he drove in with an infield out in Tuesday night's game against the Rays was the 1,834th RBI of his career, moving him ahead of Hall of Fame outfielder Dave Winfield and into sole possession of 15th place on the all-time list.
The next run he drives in will tie him with Rafael Palmeiro.
Mariners hitting below career averages
SEATTLE -- Center fielder Franklin Gutierrez stands alone among his Mariners teammates, but that's not exactly a good thing.
It's still early, but he is the only position player who has a higher batting average this season than his career average, which explains why the Mariners are having such a difficult time scoring runs.
Gutierrez went into Wednesday night's game against the Rays with a .337 batting average, 65 points higher than his up-to-date career average.
But overall, the 11 position players with at least 300 career at-bats are batting a combined 470 points below their career averages.
The discrepancy ranges from Mike Sweeney, who is batting 119 points lower than his career average (.179-.298), and second baseman Chone Figgins, who checks in with an 81-point reduction (.209-.290), to Ichiro Suzuki, who is batting nine points lower than his .333 career mark.
"For us, it's trying to get guys back to their career averages, and the toughest thing is looking at that board every night, especially the guys that are not used to that," manager Don Wakamatsu said. "There is no excuse for that.
"To us, it's not trying to focus so much on getting 10 or 12 hits a game, but to play the game the right way, get a sac bunt down when we need to, can we drive in a run when we have to?"
It wasn't a big deal at the time, but when Ichiro Suzuki grounded into a double play in his third at-bat in Sunday's game against the Rangers, it ended a personal streak of 736 at-bats without grounding into a DP. It was the longest such streak in the big leagues since Tony Womack went 918 at-bats between GIDPs from May 30, 1997, to Aug. 4, 1998. Ichiro's streak was the third longest in the Majors since 1920.
