They are three of the new guys on the Indians’ roster.

Bryan Shaw is only 25 with two big-league seasons on his resume; Scott Kazmir is more renewed than new, and to him that’s as good as it can get. Then there’s Jason Giambi, 42, who has a role that includes counseling new guys.

Kazmir already is one of baseball’s warm and fuzzy stories of 2013. Following his last productive season — when he was 12-8 with a 3.49 ERA for the Tampa Bay Rays in 2008 — Kazmir fumbled and stumbled his way out of the majors, finally landing on an independent league team in Sugarland, Texas, last year.

That’s where his renewal began in earnest, even though the only baseball farther from the big leagues than Sugarland is played on lumpy fields by slow-pitch softball teams in places like Lorain and Barberton.

“I felt like I was taking the right step, but at the same time I was in a clubhouse at a stadium in the Atlantic League, watching a big-league game on TV,” Kazmir said about his feelings of isolation. “The majors seemed like a long ways away.”

But according to him, the Atlantic League saved his career.

“One of the things that got me in trouble was thinking I had to re-create myself as a pitcher,” Kazmir said. “What I needed to do was get back to being myself and do the things that came naturally to me.”

­Sugarland, Texas, was where he found his comfort level.

“It was great,” Kazmir said. “My experience was awesome. Those guys were very passionate about the game and just all-around good people, especially the guys on my team. It was fun.”

Through all the disappointment that preceded his comeback in spring training, Kazmir never thought about quitting.

“No, it was more about the stress of wondering when it was going to happen for me,” he said. “When am I going to figure out some things? But I never gave up.”

Giambi has done it all in baseball: league Most Valuable Player, multiple All-Star Games, one World Series, and just to prove it hasn’t always come up roses, Comeback Player of the Year.

At an age when most players of his accomplishment have moved to the broadcast booth or have standing tee times at the local country club, Giambi came to camp on a minor-league contract, hoping he would latch onto a roster spot.

“I’m fired up,” he said. “I like the makeup of this team, the depth, the potential we have, the back end of the bullpen. I’m excited. We have an American League lineup one through nine. We can manufacture runs; we have speed, and we have some power. It’s impressive.”
