On Sunday, Snider was out of the Blue Jays' lineup for the second game in a row due to an ailing right wrist -- hurt during a swing on Friday night. Gaston said he was hopeful that the young outfielder would return to action on Monday, but the manager still expressed concern.
"I don't know what this is going to do to him by missing a couple days," Gaston said. "If he's not fully recovered, that might hurt him, too. I don't know. We're going to try to do the best thing for him. I don't know if he's going to be 100 percent, it's hard to hit when your wrist is bothering you."
Over his past 14 games, dating back to April 29, the 22-year-old Snider has hit . 385 (20-for-52) with four home runs, eight doubles, 11 runs scored and 11 RBIs for the Jays. Snider hit .395 over Toronto's recent 10-game road trip. During Friday's 16-10 win over the Rangers, he went 2-for-4 with a homer, but tweaked his wrist during a swing.
"He had a great road trip," Gaston said. "A lot of balls he hit on that road trip, a lot of them were fastballs and changeups, breaking balls, knuckleballs. He did it all. ... I'd like to get him back as soon as I can. Then again, we're going to be cautious with it, too."
If Snider returns healthy and continues to perform well at the plate on a consistent basis, Gaston said he would not rule out moving him up in the batting order. Gaston said the left-handed-hitting Snider, who has mainly hit out of the eighth or ninth spot this season, could possibly see time in the fifth hole later this year.
"The only spot he would move up to would probably be fifth," Gaston said. "Somewhere there if [first baseman Lyle] Overbay is not doing what he'd like to do or what we'd like to see him do. I don't see any other spot than that."
Entering Sunday, Overbay -- a free agent after this season -- was batting .191 with three homers and 14 RBIs over 37 games. Gaston said he does not want to move Alex Gonzalez or Jose Bautista out of the sixth and seventh spots, respectively, adding that he prefers to alternative left- and right-handed hitters in the lineup when possible.
