Allen was with Class A Carolina for Opening Day in 2012.
"I think there were a few fireworks or something like that," Allen said with a laugh.
Needless to say, the 24-year-old pitcher planned on soaking in every moment of Tuesday's season opener.
"I'm super excited," Allen said. "It'd be nice if it was at home, but being here in Toronto, there's a lot of buzz with them with their offseason acquisition, and with us with our offseason acquisitions. It's here in the dome. It's going to be loud. It's going to be fun."
Allen is one of three Cleveland players experiencing Opening Day in the Major Leagues for the first time. Third baseman Lonnie Chisenhall and right-handed starter Zach McAllister were also on a big league roster to start a season for the first time in their careers.
"It's definitely another thing that I've always wanted to be able to do," McAllister said with a smile. "To be able to check that one off the list is pretty exciting. We're ready. I think everyone is ready to get out of Arizona and get the season started. Spring Training was longer this year, and I think everyone is anxious and excited to see what can happen."
Allen agreed that it was great to finally start the season.
"Anywhere you're at," Allen said, "whether it's college, high school, you've been waiting the whole offseason, the whole spring, you've been waiting for Opening Day. You're waiting for the season to start. That's today. We're excited to get it under way."
