Snider jammed his wrist diving for a ball in the third inning of a Triple-A game Thursday night and exited the contest immediately after.
The 24-year-old was off to a fast start with the Las Vegas 51s in the Pacific Coast League after losing out on Toronto's starting left fielder's job to Eric Thames in Spring Training.
Snider, a 2006 first-round Draft pick, entered Thursday night's contest riding an 18-game hitting streak, but went 0-for-1 in two plate appearances.
"He's driving the ball to all fields," Farrell said of Snider, who is batting .400 through 19 games. "He's been in a good place offensively. He hasn't been so pull-oriented, his instincts on the basepaths have been consistent with what we've seen and his defense has been solid. Offensively, he's been using the whole field."
Entering Friday's game, Snider ranked in the PCL's top five in batting average, on-base and slugging percentage, OPS, doubles and total bases, while leading the league with 23 RBIs. He has also added four homers and two stolen bases, while walking 11 times.
Despite Snider's strong month, Farrell reiterated that Thames is Toronto's starting left fielder, although he said the club is always evaluating its options.
Although Snider remains behind Thames on the depth chart and has been up and down between the Minors and Majors for much of his career, Farrell still has high regard for the Kirkland, Wash., native.
"He's a talented guy, we like him a lot," Farrell said. "He's going to have a very good Major League career."
Snider has appeared in 232 games since making his Major League debut at Yankee Stadium in 2008, but has never played more than 82 games in a season.
