A corner infielder who primarily plays third base, the Dodgers are considering Fields to be the right-handed bat off the bench who can back up at third base. Infielders Justin Sellers and Luiz Cruz are also in the mix.
The Dodgers, and especially manager Don Mattingly, had hoped that last spot would go to Jerry Sands, but he struggled at the plate and played himself into a Minor League demotion to get his swing sorted out.
Fields played five innings in left Thursday and Cruz played four innings as Mattingly wanted to see if both can handle the position. Cruz has more experience there from time in the Mexican League.
"I really don't feel we've totally made that decision yet, there have been so many moving parts," said Mattingly.
Fields is batting .300, Sellers .333 and Cruz .259.
It's possible that the decision could be put off until the end of the Freeway Series against the Angels next week.
