White Sox recall Zach Stewart

MINNEAPOLIS -- Life without the six-man rotation didn't last very long for the Chicago White Sox.

The team announced after Friday's victory over the Minnesota Twins that right-hander Zach Stewart will be recalled from Triple-A Charlotte and pitch Saturday.

To make room on the roster for Stewart, right-hander Brian Bruney was designated for assignment. Jake Peavy, who was scheduled to start Saturday, will be pushed back a day to Sunday.

It isn't clear if the White Sox will remain in a six-man setup the rest of the season, if Stewart will then go to the bullpen after the start or if he will be sent down following the outing. He was obtained from the Toronto Blue Jays on July 27 along with Jason Frasor in the deal that cost the White Sox Edwin Jackson and Mark Teahen.

When Jackson was with the White Sox, the team was operating out of a six-man rotation. That setup was mostly due to Phil Humber's early-season success.

Now that Humber has cooled off, another rotation option if Stewart is successful is to make Humber a long man. Manager Ozzie Guillen said before the game that he is concerned about Humber's innings total this season.

"This is not in the back of my mind buy we have to be aware that this guy never threw 140-whatever innings in the past," Guillen said. "Minor league innings, that is [expletive]; that is nothing. Minor league innings compared to here I think is double because you have to grind it out every pitch."

Peavy, who had surgery a year ago to re-attach his latissimus dorsi muscle continues to work on regaining full strength. He appeared to turn a corner in his last start when he allowed three runs in seven innings to the Yankees and appeared to get stronger as the game went on.

In three starts with the Blue Jays this season, Stewart was 0-1 with a 4.86 ERA. In four minor-league seasons he is 18-14 with a 3.07 ERA. In one start for Charlotte, he took the loss while giving up three runs and 10 hits in 6 1/3 innings.

When Stewart was obtained in the July 27 trade, general manager Kenny Williams made it a point to mention that the Blue Jays were about to recall the right-hander before the deal went down.
