"Everything is great. I have no pain and feel real good," Chacin said. "I hit my spots real well I didn't struggle at all today and real happy with the work I had today."
Toronto has had its pitching injury troubles and Chacin's return will help an overworked staff.
The Toronto Blue Jays left-hander worked five strong innings against the Scranton/Wilkes-Barre Red Barons, throwing 77 pitches, 47 for strikes. The 25-year old from Venezuela allowed two runs on six hits while walking one and striking out six.
"I asked Mike (catcher Mike Mahoney) what he felt on Chacin's pitching and he said he had better movement today. His breaking ball was sharper, his changeup was moving down well, and he thought he commanded the ball well," Syracuse pitching coach Rick Langford said.
"He got around some of his cutters which is a big pitch for him, but did throw some good ones.
From his first (rehab start) to this one I think he's ready."
The Blue Jays rotation juggling could come to an end after an off day for Toronto on Monday.
Chacin, who has been on the disabled list with a sore elbow since June 10, should rejoin the rotation Tuesday, when Toronto starts off a three-game series against the Tampa Bay Devil Rays.
Chacin will leave Syracuse Thursday morning and meet the team in Minnesota.
"I'm ready to pitch against Tampa Bay on Tuesday," Chacin said.
