CHICAGO -- Cubs outfielder Justin Ruggiano was busy doing extra exercises with the athletic trainers early Thursday as he tries to deal with some tightness in his groin.
Ruggiano has not played since Tuesday. He was batting .378 with seven doubles, two homers and 14 RBIs in his last 21 games since June 25.
Cubs manager Rick Renteria said Ruggiano was feeling better Thursday.
"It's important that we make sure he maintains work with [the trainers]," Renteria said.
