But as Jones ran toward home, manager Mike Redmond was prepared to argue, with the contention that Rosario was blocking the plate without the ball. In the Marlins' judgment, Jones would have been denied a lane to slide.
"I would have gone out there for that, absolutely," Redmond said. "It just looked like a normal play on any normal year where he was blocking the plate and was going to catch the ball and get the guy out. He would have slid into him.
"He was definitely, in my opinion, blocking the plate without the ball."
Because of the rule change, runners can no longer barrel over catchers. But the catcher must leave an opening for the runner. If not, the runner can attempt to dislodge the ball without sliding.
