Storen, out all year after April surgery to remove a bone chip from his right elbow, has pitched in five minor league games. Sunday, Storen allowed four runs in 2/3 of an inning, giving up three hits, a walk and a home run.

Pitching coach Steve McCatty said Storen had good velocity, but too often left the ball up in the strike zone. McCatty is no longer worried about Storen building arm strength, but instead wants Storen to be more consistent with command. Given the path of his season, some hiccups are to be expected.

“I think his outing was fine,” Johnson said. “I talked to the pitching coach down there. The manager felt like probably one more outing and his command would get a little better, that his breaking ball would be more consistent. I’m not worried about his velocity or the strength of his arm. I think his arm is in great shape.”

Storen’s next, and likely last, rehab appearance will come with Harrisburg.
