CHICAGO -- Right now, the Chicago White Sox are asking starting pitcher Francisco Liriano to make a few adjustments to his delivery that they think will help make him an impact pitcher down the stretch.

“[Pitching coach Don Cooper] wanted me to stay tall and not get too low,” Liriano said. “Another thing he wants me to work on later on. But he told me for now to go out there and try to do your job and make a good pitch and try to go deeper in the game and not do too much. Just be who I am. We'll see.”

On Sunday Liriano will make his home debut as a member of the Sox, who acquired him from Minnesota on July 28. Liriano threw the first no-hitter of last season in Chicago on May 3, and in 11 games at U.S. Cellular Field, including eight starts, Liriano has a 3-4 record with a 5.77 ERA.

Liriano is looking for his first win since the All-Star break, although he had an admirable debut for the Sox last Tuesday against his former team, allowing two runs on four hits over six innings. Liriano said he’s never been a part of a six-man rotation, which the Sox are experimenting with right now, and that he planned to talk to Cooper about how he will prepare in between starts if things remain the same. He'll pitch on a regular four days rest on Sunday.
