Pinto suffered concussion-like symptoms after he was hit on the back of the head three times by an Adam Jones backswing on Saturday. He indicated earlier in the week that he could get into a game this weekend.
"I was able, for the most part, to keep the ball on the ground," he said. "I felt like I didn't make too many mistakes and the ones I did, they hit. That's going to happen."
Cahill, who has a 4.50 ERA through three spring starts, said he feels better about his command and ability to repeat his delivery than in past years.
"I think the misses are a lot better," he said. "They're competitive misses. They're not yanks in the other batter's box. Most of the misses are down, which leaves less room to get hurt."
It will be Storen's first outing since he underwent surgery to remove the hook of hamate bone from his left hand back on March 13. Strasburg will also make his first appearance since suffering an ankle injury on March 20.
"He got some treatment a couple of days after his last start and in his bullpen he was a little dead," Harkey said. "It was a perfect time to do it now in March than do it in April."
Hellickson threw a bullpen session Thursday instead of making his minor-league start. He is still scheduled to pitch Saturday against the Royals.
Hellickson is 2-1 with a 5.87 ERA in three spring starts.
