CHICAGO -- Darwin Barney finally got to hold his 2012 Rawlings Gold Glove Award.
The Cubs' second baseman was presented the trophy prior to Friday's game against the Giants. Barney's teammates came out of the dugout to applaud him during the ceremony, which included manager Dale Sveum and general manager Jed Hoyer.
"It'll be good to actually see it," Barney said. "It's exciting to get it and start the campaign for a new one."
Sveum said it's a special day for Barney.
"The Gold Glove is one of those unsung trophies that go unnoticed sometimes, and it's nice for everybody to see it -- as well as some other players -- to see that award," Sveum said. "It's probably one of the nicer trophies there is."
Does Barney have a spot at home for the trophy?
"I kind of plan on holding it for a couple days," he said, smiling. "My wife will have to move to the couch for a couple days."
He's kidding, Lindsay.
"Last year is over and done with," Barney said. "You can reflect on that when the time comes. Right now, my focus now is getting my mind and everything ready for Tuesday or Monday, whichever day I play."
Barney will begin a Minor League rehab assignment with Triple-A Iowa on Saturday, and if all goes well, he will rejoin the Cubs on Tuesday. He's on the disabled list with a left knee laceration, which he suffered March 30 when he slid into the right-field wall at Minute Maid Park. He got the stitches removed on Friday.
"I feel like I'm ready now," Barney said. "I felt like I was ready a few days ago. It's just a matter of getting that first slide out of the way. I've kept my arm in shape. I've seen pitches. It wasn't an injury that I couldn't go and do things. I could still be active. I feel I'll be ready for when I come back."
Couldn't he pick someplace warmer to rehab?
"They left it up to me, and [Class A] Daytona was thunderstorms all weekend," Barney said. "[Double-A] Tennessee is probably the best weather. I decided on Iowa. It's going to be cold here, so might as well get some at-bats with your hands frozen so you're ready when you come back."
Sveum wants Castro to be more aware on defense
CHICAGO -- Starlin Castro has the physical tools to be a star shortstop. Now, the Cubs are trying to develop his mental skills.
On Friday, Castro and second baseman Darwin Barney did some early work with Cubs infield coach David Bell. The two middle infielders have yet to play in a regular-season game because Barney is on the disabled list with a left knee laceration, but he's expected back Tuesday.
Castro made his third error in nine games on Thursday, which led to a Giants run. The Cubs lead the Major Leagues with 10 errors.
"These errors aren't because of physical ability," Cubs manager Dale Sveum said of all the miscues, not just Castro's. "It's awareness and understanding the situation and who's running. I think we've made half our errors on pure non-awareness of how much time we had to make a play or a throw."
Physically, Castro has the talent. How do you improve the mental part of the game?
"That's the million-dollar question about slowing the game down," Sveum said. "When we say 'slow the game down,' it doesn't mean make the ball go slower or the pitch go slower. It's how can you in your mind -- before a ball is hit to you, before you step in the batter's box -- how can you go over the situations in your head before the ball is hit to you?
"Those are the things, whether you're baserunning or hitting or fielding or pitching, how do you slow the game down in your mind and go over all the scenarios that can happen in your area?"
Clevenger gets first start at third in Majors
CHICAGO -- Steve Clevenger was a middle infielder before he was converted to catcher in the Cubs' Minor League system, but on Friday, he was at third base.
Clevenger got the start against the Giants' Matt Cain, as the Cubs tried to overload the lineup with left-handed hitters.
"I got my ground balls in," Clevenger said. "I feel very comfortable over there. I played infield when I was first drafted. It's nothing new to me, just getting the [repetition]."
He did play more infield this spring than in the past. Last year, Clevenger won a spot on the Cubs' Opening Day roster as a backup catcher.
"It's just a reaction position at third," he said. "It's basically catch it and throw it."
He's also prepared as far as equipment.
"I always keep my infielder's glove broken in," he said.
"If he's going to be here, he has to play," manager Dale Sveum said of Clevenger, who is the third catcher on the Cubs' roster. "It's time to get him in the lineup against Cain and see what happens."
Third baseman Ian Stewart, on the disabled list with a strained left quad, has been rehabbing at extended spring camp, and he played four innings on Thursday, hitting a couple of doubles. Sveum said he expects Stewart will begin a Minor League rehab assignment soon.
Cubs to honor Robinson on Tuesday at Wrigley
CHICAGO -- The Cubs will honor the 66th anniversary of Jackie Robinson breaking baseball's color barrier on Tuesday at Wrigley Field, when all uniformed personnel will wear his retired No. 42.
In 1997, under the direction of Commissioner Bud Selig, Robinson's No. 42 was retired across all of Major League Baseball in an unprecedented tribute.
"We're happy to join all of Major League Baseball on this historic occasion," Cubs chairman Tom Ricketts said in a statement. "Jackie Robinson is a true American hero, and we are all greatly indebted to his contribution to not only baseball, but to American history and culture."
As part of the pregame ceremony before the Cubs face the Rangers in an Interleague game, Hall of Famers Ernie Banks and Billy Williams will be recognized. Banks, who was the first African-American to play for the Cubs, considered Robinson a mentor during their time in the Majors. Banks and Robinson also share the same birthday, Jan. 31.

More on Jackie Robinson Day
Williams broke into the Majors not long after Robinson and Banks, and credits Robinson with being the pioneer who opened the door for all baseball players of color.
Rev. Jesse L. Jackson Jr., founder and president of the Rainbow Push Coalition, will throw one of the first pitches. Jackson and Robinson were friends, and Jackson gave the eulogy at Robinson's funeral in Brooklyn, N.Y.
John C. McGinley will join Jackson for a first-pitch assignment. McGinley stars as the Brooklyn play-by-play announcer Red Barber in the movie "42: The True Story of An American Legend." Barber was the voice of the Dodgers from 1939-53. McGinley will also serve as the guest conductor for the seventh-inning stretch.
After the game, Cubs Authentics will auction a game-worn No. 42 jersey signed by all Cubs players and a flag from the roof of Wrigley Field. Nearly 50 "42" flags will adorn the Wrigley roof for the game. Proceeds will go to Chicago Cubs Charities.
The Cubs will host more than 300 Chicago Public School high school baseball players at Tuesday's game in recognition of the celebration. Several CPS baseball players will be recognized during the pregame ceremony.
