Victorino's absence has created more playing time for Mike Carp, No. 3 prospect Jackie Bradley Jr. and Jonny Gomes. Carp and Gomes have started two games, while Bradley has started one. Daniel Nava has started all four in right field.
"We have a number of quality players we can pick from," Farrell said. "With the things we are dealing with when it comes to Grady [Sizemore] and Shane [Victorino], we have very good depth and good young players."
Carp was penciled into left field for Friday's home opener against the Brewers, while Sizemore started in center field and Nava was in right field.
Farrell's said his decisions are based on versatility, matchups and where the team is playing.
"Nava can play in both corner outfield spots," Farrell said. "It is exciting to rotate so many good players through the lineup."
