Jose Fernandez is starting to throw with force as he recovers from Tommy John surgery.

The right-hander made 25 tosses on Friday, the second throwing session he has completed since the surgery.

"Feels like I never had surgery and I never stopped throwing," Fernandez said. "It's weird because you think you will feel it. You guys saw there, the ball's just coming out of my hand incredible."

He needed about five minutes to complete the 25 throws to Marlins athletic trainer Sean Cunningham, who winced occasionally as Fernandez's throws from about 30 to 45 feet neared his glove.

"The progress in 4-1/2 months is really incredible," Fernandez said.
