BOSTON (AP) -- Eric DuBose shut down Boston in his second major league start and the Baltimore Orioles beat the Red Sox 4-2 to sweep Friday's day-night doubleheader.
The Orioles won the opener 10-4 as Tony Batista's two-run single highlighted a seven-run seventh inning.
Baltimore has swept all three doubleheader it has played this season.
After the Orioles ended Boston's four-game winning streak in the opener, DuBose (1-1) limited the Red Sox to one run in six innings.
DuBose, who lost his major league debut to Kansas City on May 4, scattered four hits. Jorge Julio pitched the ninth for his 28th save in 34 opportunities.
Luis Matos, who went 5-for-9 on the day, hit a three-run double to cap a four-run burst in the second. An error by third baseman Bill Mueller keyed the inning.
Nomar Garciaparra hit a sacrifice fly for the Red Sox in the third. In the eighth, Jason Varitek drew a bases-loaded walk to pulled Boston to 4-2.
Casey Fossum (5-5), activated from the disabled list earlier in the day, lost in his first start since June 7. All four runs against him were unearned, and he allowed six hits over 5 1-3 innings.
In the opener, the Orioles trailed 4-3 in the seventh when Brook Fordyce singled and Brian Roberts walked to lead off the inning.
Matos hit a tying double that chased Boston starter Derek Lowe (11-6). Scott Williamson struck out Jeff Conine and intentionally walked Jay Gibbons before allowing Batista's two-run single.
The Orioles broke the game open later in the inning on RBI singles by Jack Cust and Deivi Cruz and a two-run triple by Fordyce.
The Red Sox had taken a 4-3 lead an inning earlier on back-to-back homers by Trot Nixon and Doug Mirabelli. Nixon hit a two-run home run, his 22nd of the season, and Mirabelli followed with a solo shot.
Rick Helling (7-8) picked up the win, allowing four runs on nine hits while walking one and striking out five in six innings. It was his first victory since July 9.
Garciaparra's solo home run in the first inning gave the Red Sox a 1-0 advantage. It was the first time in Garciaparra's career he has homered in four consecutive games.
The Orioles took the lead in the second on a pair of RBI groundouts from Gibbons and Batista and made it 3-1 with an unearned run off Lowe in the fifth as Larry Bigbie reached on an error by Red Sox first baseman Kevin Millar and scored on Roberts' single.
Notes: Nixon's homer was the 100th of his career. He is the 24th player in history to hit 100 home runs in a Red Sox uniform. ... David Ortiz's single in the fourth inning snapped a string of 12 consecutive extra-base hits. He had five doubles, two triples and five home runs since his last single, which was on July 26. ... The game was made up from the home opener, which was rained out on April 11. The game was then scheduled for the following day and was also rained out. ... Red Sox reliever Ramiro Mendoza was placed on the 15-day disabled list because of tendinitis in his right knee and Fossum was recalled.
