"Koji [Uehara] and I think Daniel Nava deserve consideration," Farrell said. "Those are the two guys that quickly come to mind."
Farrell did make some recommendations to AL manager Jim Leyland.
"It's more the opportunity to state your case. What are the reasons why? You take a couple minutes of his time and say your piece," said Farrell.
Nava, a regular outfielder, started at first base on Friday with a .284 batting average and 49 RBIs to his credit.
Uehara is 2-0 with a 2.00 ERA and five saves in 38 games this season.
