BALTIMORE (AP) – Rookie Scott Moore hit a grand slam to cap a seven-run third inning against Daisuke Matsuzaka, and the Baltimore Orioles ended a record 11-game home losing streak by beating the Boston Red Sox 11-5 Saturday night.

Tike Redman and Nick Markakis also homered for the Orioles, who won for only the third time in 18 games. The 11 consecutive home losses were the most for Baltimore since the franchise moved from St. Louis in 1954.

David Ortiz homered and hit two doubles for the Red Sox. The AL East-leaders led 4-1 before the Orioles rallied against Matsuzaka (14-12).

Gustavo Molina led off with a single and took third on a double by Brian Roberts before a walk to Redman loaded the bases. Matsuzaka walked Markakis to force in a run, Miguel Tejada hit an RBI single and Kevin Millar walked to push across another run.

Matsuzaka then got two straight outs before Moore drove a 2-2 pitch into the center-field seats. Obtained in the Aug. 31 trade that sent Steve Trachsel to the Chicago Cubs, Moore was 0-for-13 this season – including 0-for-8 with Baltimore – before connecting.

That concluded the Orioles’ most productive inning of the season and ended the worst outing of Matsuzaka’s major league career. The rookie gave up six hits, three walks and a season-high eight runs.

Matsuzaka has yielded at least five runs in three straight starts and in four of the last five.

Markakis added a two-run drive in a three-run fourth against Julian Tavarez. It was his 17th homer of the season, tying Tejada for the team lead.

Orioles starter Jon Leicester (1-1) allowed four runs and seven hits in five innings to earn his first big league win since Sept. 19, 2004 with the Cubs. It was his second career start; the last one came in 2005.

At the outset, it appeared that the Red Sox would be on the positive end of a rout. Boston started 6-for-12 with four doubles, a home run and a walk in taking a 4-1 lead.

Ortiz made it 2-0 in the first, hitting his 28th home run after a one-out single by Dustin Pedroia. Redman answered with a solo shot in the bottom half, his first home run since May 2005 with Pittsburgh.

The Red Sox added two more runs in the second. J.D. Drew hit a leadoff double and was at third with two outs before .237 hitter Julio Lugo and rookie Jacoby Ellsbury hit successive RBI doubles.
