Both Snider and Thames are battling for the starting position in left field, with the loser probably being sent to Triple-A Las Vegas.
Snider went 1-for-4 with a two-run double and two strikeouts. He is now batting .296 with a team-leading 12 RBIs in nine spring games.
Thames went 2-for-4, including an RBI single and a double. He has a .320 batting average this spring in nine games.
Blue Jays general manager Alex Anthopoulos has stated in recent days the importance of Thames coming off a 2011 season in which he started 77 games in the outfield, including 53 in left.
