Brayan Bello is starting to become a Yankee-killer, and that’s a pretty good way to ingratiate yourself with Boston Red Sox fans. In the Bronx on Friday night, Bello was untouchable. It’s the second-straight start against the Yankees in which Bello has gone seven shutout. According to J.P. Long, the former Red Sox director of communications and media relations, Bello’s 1.95 career ERA against the Yankees is the lowest of any pitcher this century, minimum 50 innings pitched.
