SAN DIEGO — Red Sox starter Lucas Giolito walked four straight hitters, including forcing in the game-tying and go-ahead runs during a difficult fifth inning. “I know that the way baseball works, the L doesn’t go next to my name but it should,” Giolito said. “That was really bad.” The Red Sox lost 5-4 to the Padres in 10 innings at Petco Park.

Lucas Giolito is not a morning person. He never has been, he said. As a kid, he stayed up late reading. As an adult, it’s more about video games. Either way, rising early is not his forte, and those unfortunate occasions when it is necessary require concerted effort — effort he managed to muster in recent days.
