Ryan not allowed to throw again on Tuesday

PEORIA, Ariz. -- Mariners shortstop Brendan Ryan was not allowed to throw the ball again on Tuesday, as he continued a cautious start to camp with his recovering right shoulder, leaving newcomer Munenori Kawasaki to handle much of the position work during defensive drills.

Ryan, who missed the final 11 games last season with a herniated disc, originally thought he'd be allowed to begin throwing on Tuesday. Instead, trainers held him back another day.

Ryan, 29, said he hopes to at least start playing catch on Wednesday.

"I don't think it'll be much," Ryan said. "No sliders, no curveballs, maybe a couple cutters. Mostly four-seamers."

Though Ryan tries to joke about the situation, it's not easy watching teammates warming up their arms and doing full work. He's still able to field ground balls, but isn't allowed to throw across the infield.

"It's more annoying than anything," Ryan said. "It's more like an unwanted attention type of thing. You don't want to come in with any setbacks or anything, but it's been an ongoing thing all offseason to get to this point. This is actually probably a good thing, being at this point.

"I didn't have any idea it would take as long as it did, and there would be as much affected by the herniated-disc thing. But it's something you battle forever, I guess, now, making sure my posture is good and things like that."

Kawasaki's personality showing through

PEORIA, Ariz. -- New Japanese shortstop Munenori Kawasaki handled defensive drills with the Mariners' top infield on Tuesday, as Brendan Ryan continued nursing a sore throwing shoulder. And the result was another full dose of Kawasaki's constant Japanese chatter, as infielders took ground balls and worked on situational fielding.

Kawasaki knows very little English, but he is learning teammate's names. Thus, he'll rattle off a string of Japanese and then throw in a "Seager" or "Figgy" in the middle of it, much to the amusement of players and fans within earshot.

The extroverted Ryan admitted he sees a little of himself in the outgoing Kawasaki.

"It's funny to see people react to how I see myself," said Ryan. "It's a weird third-person type of feel. It makes you think."

Manager Eric Wedge continues putting Kawasaki with the top infield group, which also has Chone Figgins and Kyle Seager rotating at third, Dustin Ackley at second and Justin Smoak and Carlos Guillen working at first.

"He's a lot of fun to be around, and he's shown himself well here early on," Wedge said. "We've got to get into games. I haven't been able to really lock in on him offensively, yet. I want to get him in games and game speed, and see how he reacts. But from a personality standpoint, he really enjoys being on the baseball diamond. And I think all of us love that, fans and professionals alike. It's fun to see."

Sherrill throws first bullpen session

PEORIA, Ariz. -- Left-handed reliever George Sherrill tossed his first bullpen session on Tuesday, getting about five minutes of throwing in, after being held off the mound the first 10 days of Mariners camp.

Sherrill, 34, had some minor discomfort while throwing before pitchers and catchers reported on Feb. 11, and the Mariners chose to just delay his start in order to avoid any problems.

"It felt pretty good," Sherrill said. "I'll play catch [on Wednesday], and see how it bounces back."

Sherrill signed a one-year, $1.1 million deal as a free agent to return to the Mariners. He pitched in Seattle from 2005-07, before getting traded to the Orioles and becoming an American League All-Star in 2008.

He pitched for the Braves last year, posting a 3.00 ERA and 3-1 record in 51 appearances, and is expected to be the Mariners' situational left-hander, if all goes according to plan.

The Mariners will hold the first of three planned intrasquad games on Friday, but pitching coach Carl Willis said he wasn't ready to disclose which pitchers will throw just yet. Sherrill is the only pitcher who hasn't been a full go thus far, however.
