Masset had two scoreless innings and five strikeouts in two appearances for the rookie-level Arizona League Reds.
"Everything feels great," Masset said on Wednesday, while in the Reds clubhouse. "After I turned the corner, my arm has been feeling really good overall, loose, strong and all of my pitches have been working well. I'm really excited with where I'm at now."
Masset has been able to throw all of his pitches thus far and has had no setbacks since just before the All-Star break in July. He senses he's getting close to returning.
"It's been a long road and it's been tough," Masset said. "There have been a lot of ups and downs. I'm finding out a lot about myself and a lot about my arm. I'm just glad to be back with the team."
Masset will throw a couple more one-inning outings, assuming he gets through Thursday. At some point, he will have a two-inning appearance and then he will try to pitch on back-to-back days.
"As long as that goes well, I will be ready to go," Masset said.
