CLEVELAND -- Perhaps it was a day that needed at least one feel-good story. For the Red Sox, Steven Wright spending his first day on a Major League roster qualified as one.

Though the circumstances that led to Wright being summoned from Triple-A Pawtucket were hardly ideal, this was a moment to soak in for the 28-year-old knuckleballer.

"It's kind of hard not to get excited, especially knowing you're coming to Cleveland, where you spent so many years and to come here and not only to get to the big leagues, but coming back to Cleveland is really nice," said Wright.

Wright was selected by the Indians in the second round of the 2006 First-Year Player Draft and was with that franchise until July 31, 2012, when he was dealt to Boston.

The reason the Red Sox had to summon Wright is because of a nagging right hamstring injury to closer Joel Hanrahan.

"We found through yesterday's follow-up evaluation with Joel it was going to be a total of five to seven days recovery time needed for the hamstring," said manager John Farrell. "Putting him on the DL was pretty clear cut. This will also give us a chance to get him a couple of rehab appearances to get back going and test it at full speed."

Hanrahan had been struggling on the mound before going on the disabled list, posting an 11.57 ERA in six outings.

Andrew Bailey, a closer for most of his career, will continue to serve in that role while Hanrahan is out.

Meanwhile, Wright can offer the Sox multiinning stints out of the bullpen.

"My wife and baby came out with me today and my parents are flying in and my brother-in-law is flying up, too," said Wright.

Originally resistant to converting to the knuckleball, Wright has now seen the payoff from his decision.

"I never thought in a million years I'd throw a knuckleball, and the fact it got me to the big leagues is a dream come true," Wright said.

Wright is wearing No. 35 for the Red Sox out of respect for the late Frank Pastore, the coach who taught him the knuckleball.
