Francis Stymies Bulls, 7-0
Francis, a 61-game winner in the major leagues, scattered seven singles, allowing only two baserunners to reach scoring position, avenging a loss against the Bulls (25-33) in May.
Chris Archer (L, 3-7) dropped his third straight start, and was the victim of a shutout for the fourth time in his seven losses. The Bats (18-39) took a 1-0 lead in the second on consecutive doubles by Danny Dorn and Bill Rhinehart.
Louisville scored four times against Archer in the fourth, highlighted by a two-run double past first base by catcher Brian Peacock.
The Bats scored two unearned runs in the sixth against Josh Lueke, with former Bull Joey Gathright doubling in the two runs.
Shawn O'Malley went 2-3 to pace the Bulls, who fell to 5-4 on their current 10-game road trip.
Archer fanned seven more hitters, increasing his International League-leading total to 76.
The shutout was Francis' first since July 24, 2006 when he two-hit the St. Louis Cardinals as a member of the Colorado Rockies.
The Bulls' road trip ends Monday night with Shane Dyer (0-1, 6.60) starting against Chad Reineke (1-3, 4.45) at 7:05 PM ET.
