The Washington Post reports Nationals second baseman Danny Espinosa said Monday he will not play in the World Baseball Classic in order to focus on rehabbing his injured left shoulder. Espinosa added he actually feels stronger now than in the past despite a torn rotator cuff. “I feel effortless when I swing," Espinosa said. "I take BP and I don’t feel like I’m having to try to put a charge in the ball. I feel like I’m strong again. I haven’t felt this strength in my shoulder like this in forever. I’ve never done the exercises that they’ve had me doing, and the amount that they’ve had me doing. I feel strong. I feel easy when I swing. I don’t feel any pain, which is awesome. I feel good. I feel strong enough to this point that nothing is going to hold me back."
