"I do like pitching there," Arrieta said Sunday. "I love the city. It's always a fun trip."
The numbers don't exactly back up Arrieta's sentiments. He's 1-3 in three career starts in Toronto while with the Orioles, and he has a 7.31 ERA.
"When the roof's opened and the roof's closed, the ball carries differently," Arrieta said. "When the roof is closed, it seems it's a little tougher place to pitch. The majority of it has to do with their high-powered offense. They have a lot of power potential -- [Edwin] Encarnacion, [Jose] Bautista, [Colby] Rasmus can hit the ball out of the yard.
"They have a high-powered offense and it's a typical [American League] East lineup, with some veteran hitters. It's a team that we know we have to approach with a certain amount of caution and a good game plan to have success."
Arrieta, who has watched the Blue Jays over 3 1/2 seasons while with the Orioles, planned on talking to Jacob Turner and Kyle Hendricks, who will start Monday and Wednesday, respectively.
Renteria said Sunday he wanted to talk to hitting coach Bill Mueller about how to use the designated hitter spot to their advantage. The Cubs gave rookie Jorge Soler a breather on Sunday as part of the plan to avoid reinjuring his legs, and they could let him DH one of the games.
