CINCINNATI — Ramon Hernandez hit a three-run homer in the first inning, and Cincinnati overcame the loss of pitcher Johnny Cueto to beat the Chicago Cubs 7-2 Wednesday night.
Cueto, the major-league leader with a 2.31 ERA, left after 32⁄3 innings because of a strained muscle in the upper right side of his back.
The right-hander was visited by a trainer and pitching coach Bryan Price with one out in the fourth inning. After getting Alfonso Soriano to pop out, a trainer and Dusty Baker went to the mound, and the manager removed Cueto.
Cueto, who allowed three hits, will be re-examined Thursday. He didn't make his first start of the season until May 8 because of irritation in his right upper arm.
