Coming off minor shoulder surgery, Casey Janssen is going to take things slowly early in spring training.

First of all, we need to realize the definition of “minor” shoulder surgery is any surgery performed on some other poor schmuck’s shoulder, not your own.

For Janssen as he goes through the first few days of camp, he has recognized that it’s going to take some extra time to pull everything together. With almost seven weeks remaining before opening day, he and the Blue Jays can afford to be patient and build him up slowly.

The surgery — conducted Nov. 16 in L.A. by Dr. Neal El Attrache, was to repair “lingering soreness” in the AC joint at the top of the shoulder, where part of the shoulder blade meets the collarbone.

A “small portion” at the end of Janssen’s collarbone was shaved down to “relieve the discomfort,” the team said.

“Casey’s a little bit behind but there’s nothing to worry about,” said manager John Gibbons. “We’re just going to take it slow. He has been around the game awhile now and as long as he’s ready opening day, that’s all we’re worried about. We’re going to be cautious.”

This does not in any way alter the plan to have Janssen as the Blue Jays closer in 2013.

“Casey’s our guy,” said Gibbons. “We have to see where Sergio (Santos) is, too. Don’t forget he missed all of last year so he has to work his way back in, too. It’s always good to have more than one guy to do those jobs.”

There are always enough high-leverage situations late in games that Santos isn’t going to be ignored.

“We’ll see how he does down here and if he’s able to break camp with us, it will mean we’re ready to pitch him in any situation,” said Gibbons.
