Carp out for rest of season due to foot injury

ARLINGTON -- An exam on Mike Carp's injured right foot revealed a partially torn plantar fascia and the Mariners first baseman will be sidelined for the final week of the season.

"It will take about three weeks to heal, so he's obviously done for the year," interim manager Daren Brown said.

Carp, who spent most of the season with Triple-A Tacoma, was injured while running out a double in Saturday's game against the Rays at Tropicana Field.

He had been recalled from Tacoma three days earlier.

Meanwhile, designated hitter Russell Branyan was having more tests done on his lower back, and although he has not been ruled out for the season, it appears unlikely that he would play in the season-ending four-game series against the Athletics at Safeco Field, which begins on Thursday night.

Right-handed reliever David Aardsma also could be done for the season.

He was supposed to play catch prior to Tuesday night's game against the Rangers, but that was canceled after he felt some discomfort in his left oblique.

Brown said right-hander Brandon League would handle the bulk of the closer duties, and if he needs a day off, rookie right-hander Dan Cortes would be the leading candidate to protect the lead.

Lopez dislocates right middle finger on Tuesday

ARLINGTON -- Mariners third baseman Jose Lopez suffered a dislocated middle finger on his right hand in the sixth inning on Tuesday night.

"They got it back in and there is no other damage," interim manager Daren Brown said after the Mariners' 3-1 victory over the Rangers. "He'll be sore and I don't see him being able to throw for the next five days, but he might be able to swing the bat in a couple of days."

Lopez was in position to field a hot shot hit by Rangers designated hitter Nelson Cruz. The ball took a wicked hop and bounced higher than Lopez expected. The ball hit Lopez's bare hand and chest.

Cruz ended up with an infield single and Lopez immediately walked off the field and went into the visiting clubhouse for treatment.

Lopez, who is finishing up a subpar season while batting .240 with 10 home runs and 58 RBIs, doubled, walked and struck out in three at-bats on Tuesday.

"He has been swinging the bat well the last couple of weeks, and has had some leadoff walks to help us score some runs," Brown said.

Matt Tuiasosopo and Matt Mangini figure to share the position during the final days of the regular season.
