Tomo Ohka has been designated for assignment by the Toronto Blue Jays.
He's someone that I thought the Rangers would look at this offseason, and seemed like a nice, low-risk signing for the Jays, although he hasn't pitched well.
Realistically, though, if the Rangers are really considering Jamey Wright or Mark Redman as a patch in the rotation, I'd rather see them look at Ohka. If he clears waivers, he'd be worth offering a minor league deal to.
