• Top pitching prospect Zack Wheeler is scheduled to pitch a simulated game in Port St. Lucie on Sunday. The right-hander strained his right oblique muscle on Feb. 27. He threw a bullpen session on Thursday.
• Outfielder Kirk Nieuwenhuis, whose bone bruise on his left knee has sidelined him for a week, aims to return to the field on Wednesday. He ran 10 minutes in the pool on Saturday.
• Following his three scoreless innings against the Astros, right-hander Jeremy Hefner threw 25 more pitches to simulate an additional two frames. "I'm throwing a lot of strikes, getting ahead for the most part," Hefner said. "I felt good. Offspeed was working well and three solid innings. ... I was happy with the outing."
