Hunter Dobbins pitched six shutout innings to beat the Yankees for the second time in a week, and the Boston Red Sox won their fourth straight game on Saturday night, 4-3 over New York. A week after saying he’d rather retire than pitch for the Yankees because his father was drafted by New York twice before being traded — and then having to defend his dad’s story midweek — Dobbins (4-1) struck out five and gave up two singles.
