Matt Wieters’s 10th-inning opposite-field RBI double gave the Baltimore Orioles a 5-4 victory and their second walk-off victory in as many days over the Philadelphia Phillies on Sunday afternoon in front of a sellout crowd at Camden Yards.

Prior to Wieters’s hit, the big plays had come from third baseman Steve Tolleson.

Tolleson had blasted a tying, three-run homer off Phillies starter Cliff Lee in the fourth inning and provided a highlight-worthy defensive play at third base.

The Orioles (34-26) won their ninth straight extra-inning game in front of a second straight sellout crowd — the announced attendance was 45,267 — and took the final two games of this series to earn their second series win and remain one game out of first place in the AL East at the 60-game mark.

It was also the Orioles’ fourth win in six interleague games this season.

Adam Jones reached base in the 10th on former Orioles infielder Ty Wigginton’s fielding error at third. That play set the stage for Wieters’s game-winning hit off left-handed reliever Joe Savery.

Before that, Tolleson was 1 for 11 in a recent slump before stepping in against Lee with two on and two outs and the Orioles trailing 4-1.

He entered the day 2 for 2 against Lee in his career with a pair of doubles.

And Tolleson launched his third homer in 85 career big league at-bats, taking a 1-2 cutter from Lee high into the left field stands.

Immediately prior to the home run, Mark Reynolds drew a two-out walk followed by Steve Pearce’s double to put two runners in scoring position for Tolleson.

On Saturday, the Orioles defeated the Phillies, 6-4, on a two-run home run by Adam Jones in the 12th inning.

Jason Hammel struggled with his control early. He threw 51 pitches in his first two innings of work but still went six innings and retired the final seven batters he faced.

Credit the Orioles’ bullpen, which allowed just one run in five innings Saturday and threw four scoreless innings, including two scoreless from left-hander Troy Patton.

After the Orioles went up 1-0 on Ronny Paulino’s RBI single in the first inning, Hammel yielded three runs in the second as the Phillies batted around.

Hammel issued two of his season-high three walks in the inning. The Phillies loaded the bases and Hunter Pence hit a two-run single, followed by a Jim Thome run-scoring single to make it 3-1.

Hammel flirted with disaster throughout the early innings, loading the bases in the first, second and fourth innings.

Philadelphia (29-33) tacked on another run in the top of the fourth on a Hammel wild pitch that allowed Pierre to score from third.

After hitting the game-tying homer in the fourth, Tolleson also made an incredible lunging stop of Pence’s hard-hit ball in the hole to end the sixth inning.
