BOSTON (AP) -- The Baltimore Orioles finally lost after opening the season with a team-record seven straight wins, beaten by the bats of Xander Bogaerts, Jackie Bradley Jr. and the Boston Red Sox 4-2 Wednesday night.
The Orioles were the last undefeated team in the majors, ending their longest winning streak to start a season since moving to Baltimore in 1954. The franchise opened 9-0 in 1944 as the St. Louis Browns.
The Red Sox snapped a three-game losing streak. Bogaerts hit a two-run double and Bradley had a tiebreaking triple.
Chris Davis hit a two-run homer for the Orioles.
Joe Kelly (1-0) labored through five innings, giving up two runs on seven hits with five walks and six strikeouts. Craig Kimbrel, the fifth Boston reliever, struck out all three batters he faced for his second save. He took the loss in the first game of the series, giving up a three-run homer to Davis.
Ubaldo Jimenez (1-1) gave up four runs on six hits and four walks in five innings.
