Peavy tells Sox not to alter their plans

CHICAGO -- Jake Peavy has convinced the White Sox that he will be ready to return to his regular spot in the rotation on Thursday.

Peavy made his last start on Wednesday, throwing 104 pitches, then turned around Saturday and threw 55 more pitches in relief after John Danks left early with an injury.

“He talked to us this morning and said he wanted to pitch that day; he’s ready to pitch that day,” manager Ozzie Guillen said. “When the pitcher says he wants it and doesn’t want to change anything, I’m going to give it to him.”

The White Sox could have gone to Edwin Jackson instead on Thursday. Jackson last pitched Friday, so he would have had more than enough rest. Peavy could have then moved to Friday to open the three-game series at Wrigley Field against the Cubs.

Why the rush? It might have something to do with Jackson’s struggles at Coors Field in Colorado, where the White Sox open a three-game series starting Tuesday.

In three starts at Colorado, Jackson has a 15.75 ERA. And his issue isn’t with home runs, although he has given up two there in 12 innings. He also has eight walks and has allowed 21 earned runs in that ballpark.

The reality, though, is that in his one start at Wrigley Field, he wasn’t much better. Jackson gave up eight earned runs that day.

Peavy has eight career starts at Coors Field, posting a 3-4 record there with a 4.59 ERA.
