Dominic Fletcher's RBI double sparked a five-run ninth inning and the Chicago White Sox avoided a three-game sweep with a 7-2 victory over the Boston Red Sox on Sunday.

Chicago starter Chris Flexen's winless streak extended to 21 straight starts - the longest in team history - after he was pulled with the game tied in the seventh inning. The 30-year-old right-hander gave up two runs on six hits, striking out six and walking one.

Chicago (33-111) had lost 14 of its last 15 games before rallying against Boston reliever Zack Kelly (6-3). Zach DeLoach added a two-run single in the ninth inning.

The MLB-worst White Sox are nine losses away from tying the 1962 New York Mets for the most losses since 1900, and are on pace to finish 37-125. The 1899 Cleveland Spiders hold the MLB loss record at 20-134.
