The Yankees added a pair of arms to their pitching staff before Tuesday’s trade deadline, acquiring reliever Keynan Middleton from the Chicago White Sox and starter/reliever Spencer Howard from the Texas Rangers.

Middleton went 2-2 with a 3.96 ERA and 47 strikeouts in 36.1 innings with Chicago. The Yankees sent back right-handed starting pitching prospect Juan Carela, 21, who had a 3.67 ERA and 109 strikeouts in 83.1 innings with High-A Hudson Valley.

The 29-year-old Middleton slots into a Yankees bullpen that entered Tuesday with an MLB-best 3.10 ERA. The former third-round pick boasts a mid-90s fastball, a slider and a changeup that he throws more than 44% of the time.

Middleton has also played for the Angels, Mariners and Diamondbacks, pitching to a 4.00 career ERA across seven MLB seasons.

The Yankees sent cash considerations to the Rangers to add Howard, a former second-round pick who has only appeared in three MLB games this year. He began the season on the injured list with a lat strain and has a 10.80 ERA in four relief innings.

Howard has a 7.20 ERA in 38 career games, 29 of which were starts. The 27-year-old, who began his career with the Phillies, also throws a mid-90s fastball and largely relies on his slider.
