TEX@OAK: Athletics talk about the passing of Gwynn

OAKLAND -- The A's took time on Monday to reflect on the life and career of Padres Hall of Famer Tony Gwynn, who passed away at the age of 54.

"Devastated," said right fielder Josh Reddick of hearing the news. "Possibly the greatest hitter of all time."

Right-hander A.J. Griffin, who is currently recovering from Tommy John surgery, grew up watching Gwynn in San Diego.

"You would go to a Padres game, you'd always want to see Tony," Griffin said. "He had the '5.5 hole' thing going for him all the time. He was just a classy guy, treated everyone really well."

When Gwynn was coaching at San Diego State, Griffin was able to sit down with him several times as a player at the University of San Diego.

"He was just a loving guy, just a really good guy, easy guy to talk to, liked to have fun," Griffin said. "He just had an infectious personality."

A's manager Bob Melvin played against Gwynn as a catcher.

"Another one of those baseball ambassadors that just made the game better," Melvin said. "Unique in playing his whole career in one spot, then coaching there locally, too. It's really too bad.

"He was one of the great hitters of all time, and the numbers speak for themselves."

Reddick marveled at Gwynn's ability to hit for a .338 average over such a long career.

"A guy who can hit that lifetime over a 20-year career is impressive, especially now," Reddick said. "He knew what to do at the plate. He had his plan and he stuck to it, and when he got two strikes he wasn't going to give up an at-bat.

"That's what makes a Hall of Famer."

The A's observed a moment of silence for Gwynn before Monday night's game.

Reddick hopes to rejoin roster next week in New York

DET@OAK: Reddick's two-out double cuts lead to one

OAKLAND -- On the disabled list with a hyperextended right knee, Josh Reddick will begin a rehab assignment with Triple-A Sacramento on Wednesday, and he hopes to rejoin the A's in New York next Tuesday against the Mets.

Reddick will fly to Texas on Tuesday morning before meeting up with the River Cats in Round Rock on Wednesday. He expects to play several innings Wednesday and Thursday, rest Friday and play two more games in New Orleans over the weekend.

"They want to get me comfortable as possible," Reddick said. "I'm not opposed to that by any means, taking more days than usual."

The right fielder originally believed he might only need a one-to-two game assignment, but he and manager Bob Melvin prefer to take it slow, giving Reddick time to fully recover and get some hits.

"Today's the first day of an actual full routine," Reddick said Monday, when he ran the bases at O.co Coliseum. "Got everything done besides seeing live pitching."

Reddick hurt his knee banging into the wall in Anaheim on May 31 and was placed on the 15-day disabled list on June 3. He was eligible to be activated on Monday.

In 168 at-bats this season, Reddick is hitting .214 with four home runs and 22 RBIs.

After inking deal, Chapman works out with A's

TEX@OAK: 1st-round Draft pick Chapman visits TV booth

OAKLAND -- The A's announced that they have signed Matt Chapman, their first-round pick in the 2014 First-Year Player Draft. Chapman was at O.co Coliseum before Monday's game working out with the team.

A third baseman with a rocket arm out of Cal State Fullerton, Chapman was glowing after he walked through the tunnel for the first time.

"It's an honor to be on the same field as these guys," Chapman said. "I'm just going to soak it all in and enjoy it."

After meeting Josh Donaldson, Craig Gentry and Yoenis Cespedes, Chapman fielded ground balls and took batting practice, launching several balls over the 388-foot marker in left-center field.

"It still doesn't even seem real," Chapman said. "My dream was to always play professional baseball. Having never been drafted out of high school, today my dream's coming true."

Chapman plans to head to the club's Spring Training complex in Arizona on Tuesday before joining Oakland's Class A affiliate in Beloit.

Despite boasting a 95 mph arm off the mound, Chapman has no plans of becoming a pitcher.

"I told them that I can move around and play all three spots in the infield, so I'm ready to play wherever they want me to, but I'm assuming it'll be third base," said Chapman.

"I want to play every day, that's for sure."

Chapman was with his mom, dad and sister on Monday -- and with his agent, Scott Boras, who watched his client take grounders from the A's dugout.

"He's got a big, big arm," Boras said. "It'll be one of the best throwing arms in the Major Leagues. His glove is Gold-Glove caliber."

The 21-year-old Chapman, who named Donaldson and Dustin Pedroia as two players he admires, simply enjoyed putting on the uniform.

"I wore white cleats in high school," Chapman said, "so it's pretty normal, I guess."

Worth noting

• Infielder Alberto Callaspo was reinstated from the paternity list Monday, while Andy Parrino returned to Triple-A Sacramento.

Callaspo was wearing No. 7 instead of his previous No. 18, saying simply: "I wanted a change."

• The A's reinstated infielder Jake Elmore (strained left quad) from the 60-day disabled list and optioned him to Sacramento.

• Catcher Derek Norris has been nicked by several backswings recently, and while he does not plan on changing his positioning, some recent incidents have been a bit concerning.

"I get tipped on the glove all the time, that's fine," he said. "But when you're getting backswings in the head and the neck and the shoulder blade, that's maybe something."
