SEATTLE -- Third baseman Kyle Seager was back in the Mariners lineup Monday after being limited to a pinch-hitting performance Sunday due to a sore calf. He went 0-for-4 in the Mariners' 1-0 loss to the A's.

Seager fouled a ball off his leg in the seventh inning of Saturday's game at San Diego. He stayed in and finished that game, but wasn't full speed on Sunday.

"That wasn't the best one. That one hurt a little bit," Seager said Monday. "I squared it up pretty good. But it's feeling better today."

The Mariners need Seager's bat in the lineup. Going into Monday night's series opener against Oakland, the 24-year-old from North Carolina was leading Seattle in RBIs (45) and doubles (19) and was second in home runs (10).

Seager hit .320 (8-for-25) with two home runs and six RBIs on the road trip to Arizona and San Diego, including a pinch-hit double in the eighth inning of Sunday's 2-0 loss to the Padres.

He'd gone 0-for-9 the first two games in San Diego before his pinch-hit in the finale but said he felt good at the plate throughout the trip.

"I had some good swings, but just got unfortunate," Seager said. "I hit the ball hard, but just didn't have a lot to show for it. But that's kind of the way baseball goes. Arizona went well and, from an offensive standpoint, San Diego was just one of those series. But I felt fine."

The one thing he'd like back Sunday was getting doubled off second base when Justin Smoak followed with a line drive that was caught by Padres second baseman Alexi Amarista, who had shifted over to shallow right field.

"I knew they were shifting and everything, and when he first hit it I kind of paused because of the shift," Seager said. "But I saw it go over the first baseman's head and I thought it was down. I took a couple steps and then realized he was right there, but I didn't have time to get back.

"The shift throws a little wrinkle into it, but I've got to do a better job of knowing where the defense is. So that was on me."

Ackley fighting his way through struggles

SEATTLE -- Dustin Ackley has hit leadoff or batted second for much of the season for the Mariners, but manager Eric Wedge has moved him down in the order for the past 10 days as he fights his way through a slump.

For Monday's series opener against the A's, Ackley was batting eighth. He also hit eighth in the last game of the previous homestand against the Giants, then hit sixth or seventh last week while the Mariners were playing Interleague road games with the pitcher batting ninth.

With the young second baseman mired in an 0-for-13 slump and having hit just .219 in June (16-for-73) to drop his season average to .243, Wedge said he'll continue giving him time lower in the order to work his way through some things.

"We'll leave him down there for a while, let him get himself going," Wedge said. "Ack is working hard. They're doing some things against him that obviously are making it tough on him, but it's a game of adjustments and he just has to take it back. And he will.

"He's a good player and he's going to be a real good player," Wedge said. "I'm sure he doesn't feel it right now, but in the end he'll be better for what he's going through right now. It's always hard to see that when you're in the midst of it, but he's going to be OK."

The 2009 first-round Draft pick hit .273 last season as a rookie with a .348 on-base percentage and .417 slugging percentage. He was at .243/.319/.338 going into Monday's game.

Carp, Pryor continue with rehab work

SEATTLE -- Mariners left fielder Mike Carp and rookie reliever Stephen Pryor both did some light work with their teammates in Monday's pregame as they continue rehabilitating while on the 15-day disabled list.

Carp is now 15 days into his stint since being sidelined with a recurring shoulder issue, while Pryor's 15 days will be up on Wednesday. But neither is close to returning to action yet. Carp is just starting to take light swings, but isn't throwing yet with his right shoulder. Pryor, sidelined by a strained groin muscle, is throwing but not yet running.

"[Carp] is still working, still doing the rehab," manager Eric Wedge said. "I'm hoping to get him to swing a bat here at some point within the next week or so. We'll keep him away from throwing at first, just work him with the bat and go from there. He's still a ways away.

"Pryor is going to be throwing here and working toward a bullpen at some point, sooner than later, but he's still ramping up. He's [throwing] up to 90 feet today."

Once they're ready to play, both players will need to do a Minor League rehab stint before rejoining the Mariners.

Worth noting

• When Hector Noesi went 2-for-2 on Sunday, he became just the second Mariners pitcher to record a multi-hit game. Freddy Garcia had a pair of two-hit games, one in 2000 and one in '02. Noesi and Colby Lewis of the Rangers were the only AL pitchers with two hits in a game this season.

• Charlie Furbush has recorded at least one strikeout in each of his last 16 games, the seventh-longest streak by a reliever in Mariners history. Since May 13, Furbush has struck out 27 batters in 20 2/3 innings over those 16 outings, while allowing just one run for a 0.44 ERA.

• Former Mariners pitcher Mark Langston will throw out the ceremonial first pitch before Saturday's game against the Red Sox as part of the club's ongoing series of 35th anniversary celebration.
