Just as Johnny Cueto was set to begin a rehab outing in the minors, he suffered a setback.

Cueto, who is on the DL for a strained right lat, felt soreness in his oblique muscle.

“He had a good bullpen [Monday] and he didn’t experience anything in his arm but he experienced soreness in that oblique that he hurt last year in the playoffs,” Reds manager Dusty Baker said. “So, we’ll wait and see.”

Ugh. I know Tony Cingrani is dominating the majors right now, but filling in for a pitcher like Cueto is too much pressure for a rookie, no matter how talented.

Cueto’s not shown himself to be the most durable pitcher over his career, with last year being the only one of his five where he topped 200 innings pitched. Hopefully, this soreness will be nothing too serious and the healing time will serve to make Cueto healthy and ready to finish the season strong.
