It's not hard to envision a batting order like this:
Rollins, Carl Crawford, Yasiel Puig, Adrian Gonzalez, Howie Kendrick, Yasmani Grandal, Juan Uribe and whomever starts in center field.
"Rollins is one guy we're pretty sure about," Mattingly said. "Jimmy's that leadoff guy. We don't have anyone else that fits the role. He just profiles up there."
With Puig not starting Wednesday, Mattingly has Gonzalez batting third and Kendrick batting fourth. Andre Ethier starts in center field, Chris Heisey starts in right and Joc Pederson will be the designated hitter.
Mattingly said Ethier will play all three outfield positions this spring, while he said Puig will play mostly right, but also appear in center.
The list of reserves includes Corey Seager at DH and Alex Guerrero at third base.
