Ronnie Belliard hit a two-run homer in the 12th inning to give the Washington Nationals a 3-2 win over the Baltimore Orioles on Sunday in front of 39,824 _ the largest crowd in the three-month history of Nationals Park.

The Orioles had taken a 2-1 lead in the top of the 12th on Adam Jones' single. George Sherrill (2-3) retired the first two Nationals batters in the bottom half. But Dmitri Young, Washington's last position player available, walked as a pinch-hitter.

Belliard then drove a 1-2 pitch for his sixth homer of the year into the left-field stands. Belliard's hit snapped an 0-for-13 slump.

Joel Hanrahan (5-2), the Nationals' sixth pitcher, relieved with runners on first and second and two outs in the 12th and allowed Jones' go-ahead single. He then retired Guillermo Quiroz to end the inning.

The Nationals scored in the first inning. Leadoff batter Roger Bernadina singled in his first major league at-bat. He moved to second when Cristian Guzman was hit by a pitch by Jeremy Guthrie. Elijah Dukes walked to load the bases, and Bernadina scored on an infield out by Aaron Boone.

After Jason Bergmann had shut the Orioles out for the first six innings, Luke Scott drove a ball into the right-center field stands for his 14th home run of the year _ his second in two games _ to tie the score at 1.

Bergmann is winless in his last eight starts. He last won on May 15 when he pitched seven shutout innings against the New York Mets, allowing just three hits. Since then, he's lost four games and pitched to four no-decisions. Bergmann gave up one run and six hits in seven innings.

Guthrie allowed four hits in seven innings. He walked three, struck out four and hit a batter. In four career starts against Washington, he's allowed just four earned runs in 28 innings for a 1.29 ERA, but has won just once with three no-decisions.

Guthrie also had his first major league hit _ a fifth-inning double, but he was quickly picked off.
