Cubs right-hander Adrian Sampson allowed hits to five of the first nine batters he faced before making a timely adjustment Friday.
Specifically, Sampson confused an aggressive Red Sox lineup by switching to his off-speed pitches and retired 12 of the next 14 batters. That gave the Cubs some time to rally from a four-run deficit and seize a 6-5 victory at Wrigley Field.
‘‘They were all over his heater early,’’ manager David Ross said of Sampson, who allowed a home run to Jarren Duran on his first pitch and a three-run double to No.
