The Red Sox, backed by a resilient pitching performance by Joe Kelly and some timely early hits from Xander Bogaerts and Jackie Bradley Jr., handed the surging Baltimore Orioles their first loss of the season with a 4-2 decision on Wednesday night at Fenway Park.
The Orioles came in at 7-0 -- a club record start to the season -- and had been the only remaining undefeated team in the Majors.
In five innings, Kelly (1-0) threw 116 pitches, two short of a career high.
