The Yankees brought J.A. Happ to New York to beat the Red Sox, and they are wasting no time putting that plan into action.

The team announced Thursday afternoon Happ will start Game 1 of the AL Division Series against the East rival Red Sox.

Happ has a career 2.98 ERA in 21 appearances (20 starts) against Boston, and his success against the Red Sox was thought to be one of the major factors in general manager Brian Cashman trading for him before the deadline in July.

He went 7-0 with a 2.69 ERA after coming over from the Blue Jays and started for two victories over the Red Sox in that span.

Now, he’ll be asked to replicate that success on the biggest stage yet.
