Ryan, Wells remain in Seattle to get MRIs

CLEVELAND -- The Mariners embarked on their final road trip of the season on Monday, but left behind a pair of banged-up batters.

Shortstop Brendan Ryan and outfielder Casper Wells did not make the team's trip to Cleveland, instead remaining in Seattle to receive MRIs on their respective ailments.

Ryan is sidelined with tightness in his upper back and neck, and left Tuesday's game against the Yankees. He returned to play a full game on Friday, but exited Saturday's loss to Texas in the third inning.

Wells was scratched shortly before Saturday's contest against the Rangers after feeling ill. He has just three hits in his last 45 at-bats.

"Wells has something going on with his head," manager Eric Wedge said. "We're just trying to figure out what that is."

Wedge said that infielder Chone Figgins, out for the season with a hip flexor injury, would also receive additional medical attention this week.

"We're just trying to get to the bottom of everything," Wedge said, "and make sure that when we do get into the offseason, we have as much information as we need so that everyone is going to come in healthy next year."

Ackley doesn't start for first time in a month

CLEVELAND -- Before Monday, second baseman Dustin Ackley had played in every Mariners game since July 3. Suffice it to say, the rookie earned his day off.

For the first time since Aug. 19, manager Eric Wedge did not pencil Ackley into his starting lineup. The daily grind might be wearing on Ackley, who is hitting just .103 (4-for-39) with 15 strikeouts in his last 11 games.

"He's been playing more than anybody, really," Wedge said. "He's been going at it every day. That's the type of player he needs to be. He has to fight through all this, but we still need to give him a day. With the travel, where we're at, this is a good day to give it to him."

Overall, Ackley is batting .278 with six homers and 34 RBIs in 81 games. He has been one of the few bright spots in a Mariners lineup that has produced just 3.4 runs per game, which ranks last in the American League.

"For a young hitter, he's really good at getting the barrel of the bat and squaring up the baseball," Wedge said. "He has good plate coverage, he has an idea up there. He's still learning and he's still fighting to make the adjustments to the league, but he's hanging in there."
