The 17-year veteran third baseman went 3-for-4 in Friday night's 5-4 loss to the Twins, chalking up his third home run of the season to go along with two singles and two RBIs.
"It was nice just being able to do something," Rolen said. "When you're hurt, you're hurt and you don't want to play. When I started feeling healthy again and getting some competitiveness back, that's when you kind of whet your appetite a little bit and want to get back in there."
Rolen never seemed to find his groove at the start of the season, batting just .174 with 16 hits, two homers and 11 RBIs in his first 29 games before the injury.
In four games since returning to the lineup June 18, Rolen has tallied five hits, one homer and four RBIs, for a .333 batting average.
"That's huge," said Reds manager Dusty Baker. "You just don't know how happy that makes me. He looks better, period. But he still hasn't had enough reps to get where he wants to go."
On the season, Rolen is batting .196 with three home runs and 15 RBIs.
