This would be an interesting signing and I'm curious how it will play out. The fact that multiple teams are interested means that he must still have a good amount of value.
My hazy, amateur, small sample size scouting report: I saw Toritani play two games a few years ago. I specifically remember him because he was clearly one of the elite guys on the field and seemed to be the Tigers' gamechanger. He hit a bomb to right-center the first game I saw, and then ripped a big double in the gap. He also made a couple of impressive, rangey plays deep in the hole and got the outs with strong throws. Good range, nice arm, decent pop, hustle / gamer type.
This was when he was about 29 or so I believe, so his skills may have diminished. But just thought I'd throw in a little bit of firsthand info.
