David Ortiz says Jonathan Papelbon would fit in just fine with the Boston Red Sox.

"I don't know what happened there at the [Washington] Nationals, but he was a great guy and we would welcome him back with open arms," Ortiz said. "And we need help in the bullpen. We definitely do."

Papelbon requested and received his release from the Nationals last Saturday, making him a free agent.

The Red Sox have expressed interest in bringing back the 35-year-old, who pitched for them from 2003 to 2011.

"He started here and the fans love him," Ortiz added. "Jonathan is like a brother to me. He's a great guy and an amazing teammate. His teammates were always first to him. It would be fabulous to have him back."
