Jason Giambi was so happy when he found out Monday morning that he'd made the Indians' roster that he hugged General Manager Chris Antonetti.

"I've got to admit it," said Giambi with a laugh.

Giambi will open the season on the disabled list with a back injury, but he said he's "100 percent sure" he'll be ready to play when his stay on the DL ends April 9.

"I'm so fired up that I had the opportunity to make the ballclub," said Giambi, 42. "I'm truly, truly excited."

Giambi's role will be a small one, a left-handed hitting DH against tough right-handers. In the clubhouse, he'll be the Indians' version of Yoda.

"I love the role," he said. "I believe that's how you pass the game on. I'm not worried about more or less when it comes to playing time. I'm just excited to be part of it."

Giambi will travel with the team when they open the season Tuesday in Toronto.

"It's really important for me to be there," he said. "I've spent all this time with these guys ... I really think it's important for us to get off to a good start, especially against the teams we're playing.

"I want to do anything I can to help."

The Indians' first five series will be against Toronto, Tampa Bay, the Yankees, White Sox and Boston. Giambi called the opportunity to play for manager Terry Francona and the Indians a "gift from God." At the end of last season he interviewed to be the Rockies manager, which would have ended his playing days.

"When I think of Cleveland, I think of the mid-1990s," said Giambi. "Those are the thoughts I have. Hopefully, we can get back there. I know there's a buzz in the air. All the fans who have come out here to get away from the weather are excited.

"I'm excited because they're excited. They should be because it's going to be a fun year."
