"We don't put numbers on people. I've said this for years, but obviously nobody is really listening," Cooper said. "We are putting our guys in a position that best helps our club.
"What is our best formation? No. 1 doesn't face No. 1 all the time. No. 2 doesn't face No. 2. After a week, it's all out with days off. Our No. 1 guy is the guy that's out there that day. That's our No. 1 guy, no matter whose name it is."
Cooper believes that the only time numbers really mean something is when it comes to who pitches Games 1, 2 and 3 of a playoff series. The rotation White Sox manager Robin Ventura and Cooper have set, which the pitching coach didn't make public, certainly could change over the next few weeks.
