Pineda scheduled to resume throwing sliders on Tuesday

Via Chad Jennings: Michael Pineda is scheduled to throw a full 35-pitch bullpen session tomorrow, during which he will throw sliders for the first time since having shoulder surgery last May. The 24-year-old right-hander has been gradually stretching out his bullpen work and started incorporating changeups about three weeks ago. Throwing breaking balls is a pretty huge rehab milestone because of the stress they put on the arm, so this isn’t a negligible bit of news. If Pineda comes through tomorrow’s bullpen fine and can continue throwing sliders as he builds up arm strength and stretches out, it will be an overwhelming positive development for his rehab.
