Addressing poor or inattentive play was a subject both before and after Monday's 7-3 victory over the Colorado Rockies at Wrigley Field.
Manager Mike Quade was questioned before the game about his talk with second-year shortstop Starlin Castro on Sunday in Kansas City, where Castro appeared to give up on the ball after not making a play.
"I look at things a couple of different ways," Quade said. "Young frustration that results in something afterward that's not exactly what you want, I understand once. But I'd like not to see it again. An explanation needs to be given to the kid to say, 'Look, I know you didn't make that play and you're disappointed, but the play continues on. So finish the thing.'
"And I don't want to see things like that from him. He's too good a player. He does too many things well. But that is part of it. It's not just kids. People get frustrated. Like I say, it's kind of a momentary lapse of reason. You can't have a momentary lapse of reason. I didn't think it was that big a deal, but I just think it was something that I wanted to make sure he understood."
Like all big-league managers, Quade admitted there probably are different standards for veteran players from what there are from young players as far as talking to them.
However, after Monday's game, Quade said he addressed several in-game situations with the team, including a popup that dropped between catcher Geovany Soto and first baseman Carlos Pena.
"The way you run that play, the catcher is going to make catch unless he hears somebody call him off," Quade said. "As Carlos was approaching, he wanted to let Geo know that with the sun, he didn't have a play. He tried to help Geo. He just needs to be quiet, and Geo makes the play."
Quade also said pitcher Matt Garza has to "continue to work on his fielding." Garza committed 1 of 2 Cubs errors.
Second baseman Darwin Barney hit a 3-run homer Sunday in a minor-league rehab game with Class AAA Iowa. Barney, on the disabled list with a left-knee sprain, could rejoin the Cubs on Wednesday.
"I hope he's in the lineup Wednesday," Mike Quade said. "The timing could be fantastic because after playing a split double tomorrow and having this day having to play, we need to get him back in the lineup and give some of these kids a breather."
When Barney comes back, it's likely the Cubs will send rookie infielder DJ LeMahieu back to the minor leagues.
Center fielder Marlon Byrd was set to begin his minor-league rehab Monday night at Iowa. Byrd has been on the DL for more than a month with facial fractures, the result of being hit by a pitch in Boston.
"(Byrd) needs a longer stint than Barney because of his time away," Quade said. "How long that is, I don't know. This guy might have three or four games there and say, 'I'm locked in and ready.' We'll see."
Byrd hopes to be back sometime next week, when the Cubs are in Washington. He will wear a specially designed face guard for the games he plays with Iowa.
Heading (Far) East:
Cubs farmhand Bobby Scales has had his contract purchased by the Nippon Ham Fighters of the Japanese major leagues. Scales, 33, was at Iowa. He saw big-league action with the Cubs in 2009 and 2010.
The Cubs have talked informally of having Scales back as a minor-league instructor, coach or manager after his playing days are done.
