According to Mark Gonzales of the Chicago Tribune, the White Sox have signed pitcher Tomo Ohka, who turns 32 in March. Ohka made ten big league starts in ’07 for the Jays, and the results were not pretty. He also pitched at Triple A for the Mariners and Cardinals, ineffectively.
Ohka is an interesting character. I wrote this profile of him over a year ago, but it’s still a decent look at his history. You might say he’s had a few attitude problems. Regardless, it doesn’t hurt for the Sox to have him in Triple A as insurance.
