PHOENIX — Carlos Rodon was pretty excited to face hitters at a major league venue on Monday afternoon, another step in his return from the disabled list.

Just when the White Sox left-hander will return is still to be determined. But it’s another telling sign of progress that Rodon threw 60 pitches and got up and down four times against White Sox minor leaguers at Chase Field on Monday. The exercise was the fourth simulated game that Rodon — on the 60-day disabled list with bursitis in his left shoulder — has participated in since he returned to the mound earlier this month. He said he currently views himself on an every-fifth-day schedule. Jake Petricka, who like Rodon was ecstatic to be back around White Sox teammates, also threw in the sim game as did Nate Jones.

“I’ve been itching for two months,” Rodon said. “Like I said, frustrating. Hopefully soon they’ll lift the leash off and let me pitch in a game and get back up here for my boys.

“Jake and I, we just play it by ear, listen to what they got for us and we do it.”

“We’re getting closer.”

While nobody is putting a timeline on when Rodon would return, he’s clearly advancing to a promising phase. General manager Rick Hahn watched Rodon’s outing and called it positive. Hahn said it’s encouraging that Rodon has begun to think of himself on a five-day schedule and the next step includes building up arm strength and endurance.

“He’s been out there now three or four times throwing to hitters,” Hahn said. “Each time has been a little more crisp from what I understand from the previous ones to today. Hopefully here in the coming weeks we are able to announce he’s starting a rehab assignment and we’ll have a better sense of his time frame at that point.”

The entire ordeal has been somewhat of a frustrating odyssey for Rodon. He initially believed he would be ready to return to the White Sox at the start of the month.

“Now it’s May 22nd and we’re still here,” he said. “It’s taken a lot longer than I imagined. It’s hard to be patient when your team is out here battling. I’m sitting on the backfield throwing and fielding PFP’s and waiting back here. It’s been frustrating.

“That’s all I can say, frustration.”

Rodon said he threw at 100 percent in the game. He described his command as pretty close to normal and said his stuff has begun to return.

The process has taken longer than all parties expected because it’s based on feel and “throwing with discomfort is never a good thing,” Rodon said. However, that time appears to be in the past as Rodon feels like he’s made good progress and is itching to get back on the mound.

Rodon would love to ignore his body and try to pitch through this. But after experiencing discomfort, Rodon appreciates the methodical approach.

“The competitor in me tells me to go out there, screw it, I can pitch,” Rodon said. “I’ll do it. I don’t care. But then you have to step back and know this is your career. It’s something that could affect you over a long period of time, I have to be healthy. I can’t be on the DL every other month. You know? That’s not going to work. You have to be a reliable starter, a guy who goes seven innings. We’re looking into the future. Not just this year but into the future. Obviously, hopefully I’m a part of that. Have to be healthy to help out so. It’s hard to take the reins back on myself. As you get older you know your body better, what feels right and what feels wrong. I’m understanding that in the whole process. They’re helping me pull the reins back.”
