A return to U.S. Cellular Field might be just what Toronto Blue Jays pitcher and former Sox ace Mark Buehrle needs.

On Saturday, the fast-working left-hander will make his first start on the South Side since his 12-year run with the Sox ended in 2011.

Fans will almost certainly give a warm reception to Buehrle, whose Sox highlights include a World Series in 2005, a perfect game in 2009 and four All-Star Game appearances.

“It’s nice to come back where you played for so long and hopefully get cheered,” Buehrle said Friday. “I remember Frank [Thomas] got cheered. Then he hit two home runs and started getting booed. If I pitch too good I met get booed walking off the mound, I don’t know.”

Buehrle, who still wears No. 56, has struggled since June, winning one game after a 10-1 start. He is 11-8 with a 3.31 ERA and hasn’t pitched more than four innings in his last two starts.

His counterpart on the mound will be friend and former teammate John Danks, who said Buehrle has been overlooked and underrated throughout his career.
