I'm watching for Torkelson to start walking. That's his game. He's already starting putting the barrel on the ball more and he's not late on fastballs this season so that's big progress. With the umpiring being so horrible in two of the Tigers series already it's tough to judge, but when Tork is confident and seeing the ball he's going to walk more. I have some hope he's going in the right direction.
OTOH, Greene seems to be regressing. As posted above, I think his swing is getting long and loopy. Maybe he can get that back under control without a step back to easier pitching, maybe not, but right now I think I'm willing to give Torkelson a little more rope than Riley, which is the reverse of where I have been in the past.
The other ironic thing with Riley is that he recently has a lot of trouble with low and in, which is often a happy zone for a LHH, but not for Riley.
