Darwin Barney's return Tuesday should help the Cubs not only defensively but in having a ``take charge'' player on the field.
``Barney is definitely that kind of guy,'' manager Dale Sveum said. ``He has the awareness of the situation and can slow the game down in those 15 seconds [between pitches] and know how the game can change from pitch to pitch and count to count and score to score and hitter to hitter.
``Those are things we're trying to get the rest of the infield aware of. It's something you don't really teach but have to harp on.''
Sveum pointed to Saturday's 3-2 loss to the Giants as the latest example of mental mistakes costing the Cubs.
``There was no error in the box score, but we made five mental mistakes that cost us runs.''
NOT A CLOSER CASE
The Cubs signed their one-time closer Kevin Gregg to a minor league contract Sunday, but not to take that role again for the parent team.
Gregg, 34, was released by the Los Angeles Dodgers when he declined a move to Class AAA after spring training. He had an 0.82 ERA in 11 spring appearances.
He pitched the last two seasons for Baltimore.
He had 23 saves for the Cubs in 2009 when he went 5-6 with a 4.72 ERA while dealing with knee problems in the aftermath of off season surgery.
Gregg was assigned to Arizona extended spring training.
Kuyji Fujikawa, who is on the disabled list with a strained forearm muscle, is still expected to be the Cubs closer.
