DETROIT — The Sox on Sunday promoted Craig Hansen from Pawtucket to replace Brandon Moss (appendectomy), and it sounds as if manager Terry Francona is looking forward to seeing the rejuvenated right-hander pitch.

In what may be a related, developing situation, right-hander Manny Delcarmen has continued to struggle in his role as the bridge between the starting pitcher and the dynamic duo out of the bullpen in the late innings: Hideki Okajima and Jonathan Papelbon.

Hansen, the No. 26 pick overall in the 2005 draft, struggled in the big leagues in 2006 and spent all of last season in Pawtucket, struggling there as well. This season, Hansen seems to have rediscovered the groove that made him such a high pick.

The 6-foot-6, 230-pounder was 1-0 with a 1.62 earned-run average and 17 strikeouts in 16.2 innings for the PawSox, allowing runs in only one of his appearances. Hansen had a one-day stay in Boston two weeks ago and was the losing pitcher on April 23, surrendering a homer in his 1.2-inning stint.

"We probably rushed him," said Francona of Hansen's troubles early in the big leagues after a sterling career for St. John's.

"We saw him last year throwing changeups on a 3-and-2 pitch. He's a guy who throws hard and has a nasty slider," said Francona. "He has gotten back to pitching like it's 'Me against you, let's go. If you beat me, you beat me.' The results have been very good. This is a great way to get him up here and see what he can do. It could be (he'll be up) 10 days or 10 years. This is a chance to watch him pitch.

If Hansen pitches well, he might push Delcarmen for the late-inning setup role. Delcarmen has been faltering badly. He has been scored upon in five of his last six outings, and in his only scoreless appearance, he gave up a hit and a walk in one-third of an inning.

Delcarmen hasn't been able to work himself out of his funk because in his role, Francona can't have a lot of patience. Delcarmen generally enters games with the Sox ahead, and is backed up by Okajima, so at the first sign of trouble, Francona is lifting Delcarmen and calling for Okajima.

“(Delcarmen) just hasn’t been consistent enough with his pitches and is paying the price,” said Francona.

Hansen was called upon in the sixth inning last night but didn't help himself very much, yielding two runs in 1.2 innings of work.
