The Blue Jays (13-17) are in last place in the AL East, but have won two straight - a 3-0 win over Boston on Thursday and a 2-0 victory over the White Sox (14-13) on Friday.

Both of Toronto's runs on Friday were unearned. Shannon Stewart hit a two-out, two-run single in the first, capitalizing on a throwing error by White Sox third baseman Joe Crede that extended the inning.

"When a mistake is made, you've got to capitalize on it," Toronto center fielder Vernon Wells said. "We were able to do that tonight and the two runs held up."

Shaun Marcum allowed two hits and struck out nine in 6 2-3 innings for the Blue Jays. Toronto starters haven't allowed more than two runs in any of their last six outings, posting a 1.02 ERA during that span in which they've pitched into the seventh inning in each outing. The Blue Jays, though, are just 3-3 in those contests.

Toronto looks to match a season high in consecutive wins on Saturday when it sends Litsch (3-1, 4.85 ERA) to the mound.

Litsch is coming off his best start of the season. He pitched a season-high seven innings Sunday against Kansas City, allowing two runs - one earned - and five hits in a 5-2 victory.

"I worked on my sinker the last four days and today it helped me out of some jams and keeping them off balance," Litsch said. "Being able to use both sides of the plate with command is key. That's what I've been working on and that's what I need to keep progressing."

The right-hander has never faced the White Sox.

Friday's loss was a season-high third straight for Chicago, which has scored a combined seven runs in the last four games, including Monday's postponed game against Baltimore, after scoring 20 in their previous four.

"It's a shame when our pitching staff is doing real good and we're not helping them to win games," White Sox manager Ozzie Guillen said.

Guillen said he plans to shake up the lineup Saturday, replacing Juan Uribe with Pablo Ozuna and dropping struggling Jermaine Dye to sixth in the order.

First baseman Paul Konerko (sore right thumb) is expected back in the lineup Saturday after he missed his second straight start on Friday. Konerko is hitting just .221 this season, but is 7-for-21 with six walks and two home runs in his last six games.

The White Sox hand the ball to John Danks (2-2, 3.00) on Saturday.

Danks pitched well in his last start April 26 against Baltimore, taking a perfect game into the sixth inning, but was pulled after allowing two runs and four hits over the next 1 1-3 innings. Chicago lost 5-1.

The left-hander has a 0.86 ERA over his last three starts.

In Danks' only start against Toronto, he allowed one run and four hits in five innings of his team's 4-3 loss on June 3. He did not factor in the decision.
