With Friday night's tilt less than 24 hours away, Aaron Boone has made a monster decision. 

​The New York Yankees acquired veteran lefty ​J.A. Happ to take the mound in pressure situations. This is why he'll ​pitch against the Boston Red Sox on Friday night in Game 1 of the ALDS. 

In 21 career appearances (20 starts) against the Red Sox, Happ has a career 2.98 ERA with 95 strikeouts over 117.2 innings. In 10 career appearances (nine starts) at Fenway Park, Happ possesses a 5-2 record with a 3.27 ERA.

​​Sometimes your career marks don't matter, and what you've done against that particular team in recent memory is what carries the day. Well, Happ has been even better against Boston this season, posting a 1.99 ERA in four starts against them this year.

Happ has been New York's best starter since he was acquired, going 7-0 with a 2.69 ERA in 11 starts, which is why there was a chance he could've started the Wild Card Game. 

However, with him going up against Boston in Game 1, that opens the door for him to face the team he's dominated once again should this series go to a Game 4 or Game 5. Let's see if the veteran can get the job done come Friday night.
