Steve Tolleson hit a three-run homer for the Orioles, who bounced back from a 4-1 deficit to keep Philadelphia starter Cliff Lee winless this season.
Baltimore took two of three from the Phillies, including a 12-inning win on Saturday. The nine straight extra-inning victories is an Orioles record, breaking the mark of eight set twice previously.
Adam Jones led off the 10th against Joe Savery (0-1) by reaching on a fielding error by third baseman Ty Wigginton. Wieters then launched a drive to right that hit the scoreboard, inches over the outstretched glove of Hunter Pence. The bouncing ball eluded Pence long enough for Jones to score the unearned run.
Darren O'Day (4-0) worked the 10th for the Orioles.
