Mark Trumbo has been playing first base in Morales' absence. Morales has been taking ground balls and batting practice, and is up to 80 percent of his body weight on a treadmill.

"Hisanori knows what he needs to do to be ready," Scioscia said of the veteran left-hander who excelled in multiple roles last year for the Mets.
