"It felt good all the way through. The next day, I had a little soreness," Masset said before heading to the bullpen Wednesday. "When you go through something like this, you have the spot that's hurt, but as you come back and start throwing, there are certain things that are going to pop up in your shoulder -- just tightness.
"You're training your arm to throw all over again. I've had some discomfort in certain areas, but that's kind of the process of coming back and kick-starting the shoulder again. Overall, it's doing very good."
Masset is going to make the trip with the team to San Francisco to continue his throwing program. If all stays on track, he could head to the team complex in Arizona to face hitters in simulated games.
"But I don't have a full schedule," Masset said.
Masset hopes to be able to throw in the bullpen every other day until a potential rehab assignment.
"I'm really cranking it up to get into game speed," Masset said. "I'm happy with my progress."
