BALTIMORE (AP) -- David Ortiz had three of Boston's 12 hits off Wei-Yin Chen, and the Red Sox got an effective pitching performance from Felix Doubront and four relievers in a 4-3 victory over the Baltimore Orioles on Thursday night.
Xander Bogaerts also had three hits for the Red Sox, who took two of three in this season-opening series between AL East rivals. The 21-year-old Bogaerts has reached in eight of 12 plate appearances, collecting five hits and three walks.
Boston finished with 14 hits, 12 of them singles. The Red Sox amassed 33 hits in the three games, including five by Ortiz.
Matt Wieters had three hits for the Orioles and Chris Davis had two hits and scored twice.
Doubront (1-0) allowed two runs and six hits in 5 2-3 innings, and Boston's bullpen maintained its 0.00 ERA with 3 1-3 innings of three-hit relief.
Chris Capuano got three straight outs in the seventh, Junichi Tazawa worked the eighth and Koji Uehara needed only seven pitches to retire the side in the ninth for his first save.
Boston's bullpen allowed six hits over 7 1-3 innings in the series, and the Red Sox gave up only seven runs overall.
Chen (0-1) gave up four runs in 5 2-3 innings. The left-hander yielded 11 singles, one double and did not issue a walk. He left in the sixth after Will Middlebrooks doubled and scored on a two-out single by Jackie Bradley Jr. to put Boston ahead 4-2.
Baltimore chased Doubront in the bottom half.
Chen yielded singles to four of the first six batters he faced but got a pair of double plays to avoid extensive damage. After Boston put runners on the corners and no outs in the second inning, Bogaerts scored on a double-play grounder.
The Red Sox made it 2-0 in the third. With two outs, Bradley scored from first base when a bloop single by Ortiz eluded the grasp of a diving Nelson Cruz.
Three singles, the last by David Ross, put Boston up 3-0 in the fourth. The Orioles scored two in the bottom half on doubles by Davis and Wieters, along with an RBI single by Delmon Young.
