Glen Perkins threw 15 pitches with no problems on Saturday and he continues his comeback from shoulder surgery. He still has a long way to go, and there are no plans to ramp up his schedule. He tore the labrum in his left shoulder last season, and those aren't the easiest surgeries to come back from.

The Twins aren't even sure when Perkins will be ready to pitch in games.

"He’s going to have to help steer the ship here," manager Paul Molitor said. ".He’s kind of earned that by what he’s done in the game. You just try to guard him against meeting other people’s expectations and what we hope might happen. It’s a long way back from a fairly major surgery so we’ll kind of just have to see how it goes."

One different thing about this camp is that the catchers are going through daily pitch framing drills. I spoke with prospect Mitch Garver, who really likes working on them, Jason Castro, whose strength is pitch framing, has been helping as well. The catchers will eventually work on their footwork and positioning behind the plate. That's important to make sire the umpire has clear view of the outside corner.

Umpires line up between the shoulder of the catcher and hitter, that opening is referred to as the slot. Consequently, they sometimes struggle with pitches on the outside corner. That's where the catcher can position himself to make sure the umpire has as good of a view as possible.

Interesting stuff. I'm still not sure if the pitch framing metrics are the real deal. And I read a story during the offseason that suggested that catchers with spot-hitting staffs tend to be better pitch framers than catchers with high velocity staffs. But this is what we have to work with.

I watched Craig Breslow throw in the bullpen today while testing the slow-motion option on the smartphone. I mentioned it to Breslow after the workout. He asked to see the video and grimaced while watching it. "That's too high," he said. Breslow has been working on a lower arm angle that gives him a better breaking ball. But his arm was not as low as it needed to be on Saturday.

I also attempted to Facebook live some of the throwing sessions. I didn't realize the reverse angle mode was on, so everything looked backward. Oh well, it's spring training for me, too. I believe we are going to use Facebook live more this year, so make sure you follow the Star Tribune Sports page there for more content. Today's video has been posted on my personal Facebook page, for those I have friended. Breslow's slo-mo work is on there too.
