BALTIMORE — Wei-Yin Chen allowed four hits over seven innings, Chris Davis homered and the Baltimore Orioles beat the struggling Boston Red Sox 6-0 Wednesday night at soggy Camden Yards.
Nick Hundley had two hits and an RBI for the Orioles, who yielded only one run in winning 2 of 3 from the defending World Series champions.
Chen (7-2) did not return after rain delayed the game for 1 hour, 38 minutes in the middle of the seventh. The Taiwanese left-hander had a season-high seven strikeouts, walked none and was aided by three double plays.
Rubby De La Rosa (1-2) needed only 15 pitches to dig himself and the Red Sox in a 3-0 hole. Steve Pearce walked and scored on a double by Adam Jones before Davis went deep into the right-field seats.
After play resumed in the seventh after a rain delay with Baltimore ahead 4-0, the few fans remaining watched Darren O’Day and Zach Britton each pitch an inning to complete the four-hitter.
Dustin Pedroia had two singles for the Red Sox, who have lost 7 of 9. Boston (29-36) has been blanked six times this season, twice in this series.
It was the 10th home run of the season for Davis, the defending major league home run champion. The slugger took extra batting practice before the game in an effort to break out of a 3-for-19 skid.
Chen retired the first 11 batters, six by strikeout, before Pedroia lined a single into the right-field corner with two outs in the fourth. He was thrown out by Nick Markakis trying to stretch it into a double.
After Baltimore went up 4-0 in the fourth on a two-out RBI single by Hundley, a replay wiped out the inning’s second run. Hundley was called safe at second base on a fielder’s choice as Jonathan Schoop scored, but Boston Manager John Farrell asked for a replay and Hundley was subsequently ruled out.
In the eighth, Red Sox reliever Chris Capuano walked Schoop and Markakis with the bases loaded.
