Happ will make his final start of the regular season -- and potentially tune up for a starting assignment in the AL Wild Card Game -- on Friday. Happ is coming off a no-decision against the Orioles and is 6-0 with a 2.34 ERA in 10 starts as a Yankee.
The lefty swingman is 4-2 with a 4.06 ERA as a starter this season. Johnson was last used as a starter on Sept. 2, so his pitch count figures to be limited. He is 2-1 with a 4.37 ERA in 22 appearances at home.
