Clay Buchholz pitched a five-hitter for his second career shutout, Marco Scutaro homered and scored three runs, and the Boston Red Sox beat the host Baltimore Orioles, 11-0, last night to ruin the managerial debut of Juan Samuel.

Kevin Youkilis and Adrian Beltre also homered for the Red Sox, who have won six straight on the road.

Buchholz (8-3) walked one and struck out two in his third career complete game and first shutout since he no-hit the Orioles on Sept. 1, 2007. The righthander is 5-0 with a 0.99 ERA in his last five starts and has won nine successive starts on the road, a streak that began last August.

Samuel, a former Phillies second baseman and Wall of Fame honoree, was hired as Baltimore's interim manager yesterday morning after the team fired Dave Trembley. In explaining the move, president of baseball operations Andy MacPhail said he was "hoping to ignite a spark."

It didn't happen against the Red Sox, who led 3-0 after one inning and 7-0 after four.

Orioles starter Chris Tillman (0-1) allowed seven of the 11 batters he faced to reach base. The righthander yielded four runs, five hits and two walks in 1 1/3 innings, the shortest outing by an Orioles starter this season.

Despite the change in managers, the Orioles experienced a familiar sensation in the top of the first. After Boston used a single and two walks to load the bases with no outs, Victor Martinez hit a run-scoring grounder and J.D. Drew followed with a two-run double. Baltimore has been outscored 40-18 in the first inning this season.

The second inning wasn't much better. Dustin Pedroia hit an RBI single to chase Tillman and make it 4-0. Youkilis connected off Mark Hendrickson with two on and two outs in the fourth. All the runs were unearned because Orioles catcher Matt Wieters let a third strike slip through to the screen, a passed ball that allowed Bill Hall to reach first.
