Problem: Coming off their easy road win over the Rams, the Vikings went home for a Week 6 inter-conference duel with the Baltimore Ravens. Minnesota got off to a fast start in the first quarter with quarterback Brett Favre completing a 19-yard touchdown pass to tight end Visanthe Shiancoe and a 4-yard touchdown pass to wide receiver Bernard Berrian. Afterwards, the Ravens got the only points of the second quarter as kicker Steven Hauschka getting a 29-yard field goal. In the third quarter, the Vikings picked up where they left off with a 40-yard field goal from kicker Ryan Longwell. Baltimore responded with a 22-yard touchdown run from running back Ray Rice, yet Longwell helped out Minnesota by nailing a 22-yard field goal. Afterwards, an action-packed fourth quarter ensued. Minnesota increased its lead with Favre hooking up with Shiancoe again on a 1-yard touchdown pass, but the Ravens continued to hang around as quarterback Joe Flacco found wide receiver Mark Clayton on a 32-yard touchdown pass. The Vikings replied with Longwell's 29-yard field goal, but Baltimore took lead for the first time in the game as Flacco hooked up with wide receiver Derrick Mason on a 12-yard touchdown pass and Rice running 33 yards for a touchdown. Minnesota then regained the lead as Longwell booted a 31-yard field goal after a 58-yard pass from quarterback Brett Favre to wide receiver Sidney Rice. The Ravens got a last-minute drive into scoring range, but Hauschka's 44-yard field goal attempt went wide left, preserving the Vikings' perfect season. With the win, the Vikings acquired their first 6-0 start since 2003 (unfortunately that team did not make the playoffs). Also, dating back to Week 17 of the 2008 season, Minnesota has won seven-straight regular season games for the first time since 2000.
