(Sports Network) - Now with their eight-game losing streak behind them, the Colorado Rockies will shoot for a series split with the Houston Astros when they wrap up a four-game set this afternoon at Minute Maid Park. Colorado posted its first win on Saturday since sweeping the New York Yankees in three games at Coors Field from June 19 - 21. Jeff Francis tossed seven shutout innings and scattered just three hits with four walks and four strikeouts before LaTroy Hawkins and Jeremy Affeldt completed the 5-0 win. Kaz Matsui finished 3-for-5 and scored twice for the Rockies, who are eight games off the lead in the NL West standings. Matt Holliday ended 2-for-5 with an RBI and a run scored in the win. Rodrigo Lopez will try to get back in the win column on Sunday when he takes the mound for the Rockies. Lopez, who is 4-1 with a 4.09 ERA in nine starts this season, suffered his first loss of the 2007 campaign on June 26 against the Chicago Cubs. He was reached for eight runs and nine hits over 4 2/3 innings of an 8-5 loss. The right-hander has faced Houston just once in his career on June 15 of the 2005 season. Lopez pitched eight brilliant innings of one-run ball in a 5-1 triumph at Camden Yards as a member of the Orioles. Meanwhile, the Astros had a two-game winning streak stopped and lost for the seventh time in 10 tries yesterday. Craig Biggio had two of the four hits for the Astros, who are 13 1/2 games off the lead in the NL Central division. Former Rockies starter Jason Jennings, who was traded to the Astros in December in a multi-player deal, allowed three runs on five hits with six strikeouts and two walks over seven innings for the loss. Houston will hand the ball to Wandy Rodriguez for Sunday's series finale and he is 4-7 with a 4.57 earned run average over 15 starts this season. Rodriguez is just 1-2 over his last four starts and was saddled with the loss his last time out on June 26 against Milwaukee. He gave up six runs through five innings of an 11-5 setback to the Brewers. The left-hander is 2-1 with a 4.88 ERA in four career starts against Colorado. He beat the Rockies on June 5 this season after permitting just one run in five innings of a 4-1 victory at Coors Field. The Rockies took two of three games from Houston at Coors Field earlier this month and have claimed seven of 12 matchups between the clubs since the beginning of the 2006 season.
