The White Sox’ starting rotation includes two veterans who might be fifth starters on different teams and three young pitchers with pedigree but who are far from proven. With Carlos Rodon recovering from left shoulder surgery, the Sox’ starting five six weeks from now is shaping up as (not necessarily in order) James Shields, Lucas Giolito, Reynaldo Lopez, Miguel Gonzalez and Carson Fulmer. Gonzalez, 33, who was traded to the Rangers Sept. 2 before returning as a $4.75 million free-agent four weeks ago, won seven games last season to tie Derek Holland for the team lead. It all starts with pitching and the rotation is perhaps the biggest reason why the Sox are at least a year away from competing. It is a mixed bag of growing pains (Giolito, Lopez, Fulmer) and aches and pains (Shields, Gonzalez and Rodon were on the disabled list for lengthy stretches last season).
