The Blue Jays drafted Thames in the seventh round in 2008, and Thames appeared in a combined 141 games with them over the past two seasons.
The outfielder knows the adjustment will take some time, and he's glad to get the process under way.
"I just want to get the first few games out of the way so I can just get used to ... the new team and everything," Thames said. "It's weird just because everybody I went up the system with is somewhere else. I don't know many of these guys, besides yesterday meeting all of them and guys in the Fall League."It's no pressure, [though], it's just go out there and play hard and help the team win, and guys respect that. That's how team unity's built."
