"As long as fastballs feel good tomorrow, maybe we'll get to spin some [offspeed] stuff off of the mound on Thursday," Masset said. "We're making big strides right now. It feels good."
Masset has been throwing breaking balls on flat ground for a few days. On Saturday, during his first bullpen session at Citi Field, he threw 20 fastballs.
"The biggest thing was I was comfortable and the ball was coming out of my hand OK," he said. "I was at about 80 percent. Hopefully, we'll start climbing from there and let it go some more."
