"Probably so," Gaston said. "You've got to remember, he's another guy that takes home a pretty good paycheck, too."
Encarnacion -- sidelined since April 15 with a sore right shoulder -- is under contract for $4.75 million and is eligible for free agency after this season. The Blue Jays acquired Encarnacion from the Reds as part of the July 31 deal that sent third baseman Scott Rolen to Cincinnati last season.
While Encarnacion has been on the DL, right fielder Jose Bautista has filled in nicely at third base, while Fred Lewis and Travis Snider have performed well as Toronto's left and right fielders, respectively. Encarnacion is expected to be ready to return within the next two weeks and Gaston is not sure how the lineup will be altered.
"I don't know yet," Gaston said. "We don't know what were going to do with that. Hopefully it works itself out some kind of way. It's going to be interesting."
