(Sports Network) - The Pittsburgh Pirates will try to match their season high for consecutive wins tonight when they continue their three-game series with the Chicago Cubs at PNC Park.

The Pirates won their fourth game in a row in the series opener on Friday, one shy of their season-high five straight wins set from April 22-27. Freddy Sanchez and Xavier Nady both homered in the 8-4 victory yesterday.

Ryan Doumit finished 2-for-4 with an RBI and two runs scored for the Pirates, who improved to 6-2 on a 10-game homestand. Jose Bautista ended 2-for-4 with an RBI in the win.

Paul Maholm (5-11) gave up four runs on five hits with three walks and five strikeouts over seven-plus innings for Pittsburgh, which announced earlier in the day that CEO Kevin McClatchy will step down from his position at the end of the 2007 season.

Mark DeRosa went 1-for-3 with an RBI for the Cubs, who have still won 11 of their last 14 games and trail Milwaukee by 5 1/2 games for the lead in the NL Central. Right-hander Jason Marquis (6-5) allowed six runs on eight hits with three walks and three strikeouts over 4 2/3 innings for Chicago.

Cubs starter Ted Lilly aims for his fourth straight winning decision with tonight's outing. Lilly is coming off back-to-back wins and hasn't been defeated since June 5 at Milwaukee -- a span of five starts.

The left-hander was solid on Monday against the Nationals, hurling seven innings of one-run, three-hit ball with three walks and five strikeouts in a 7-2 victory that improved Lilly to 7-4 with a 3.84 earned run average.

Lilly has made two starts against the Pirates this season and didn't factor into the decision of either outing. He has a lifetime ERA of 5.52 in four games (two starts) against Pittsburgh.

John Van Benschoten will take the hill for the Pirates tonight still in search of his first win of the 2007 season. He lost his first two outings of the year, including his season debut on June 16, and has since posted back-to-back no-decisions.

Against Milwaukee on Monday, the right-hander allowed three runs on three hits with two walks and five strikeouts over six innings of his team's eventual 10-3 loss.

Van Benschoten, who was 1-3 in 2004 with Pittsburgh, has never faced the Cubs. He is looking for his first victory since posting his only major league win on September 10, 2004 against Houston.

Pittsburgh now holds a 4-3 edge in its season series with Chicago this year.
