This is a must win for the Yankees as they are 6.5 back in the division. They have their ACE on the hill and he has been dominant vs Boston especially after a Yankees loss. Severino is coming off his shortest outing of the year, allowing six runs on eight hits in 4 1/3 innings against the Royals. Look for a big performance here tonight from him. Rick Porcello has been hit hard by the Yankees and he struggles at home where he has a 5.10 ERA in 10 starts this season. Look for Luis Severino to come out strong and then the Yankees bullpen to close the deal in the 7-8- and 9th innings.
