White, 28, had an 888 OPS in 237 plate appearances for the Astros last year, but has struggled in 2019, putting up a .225/.320/.330 slash line in 253 plate appearances for the Astros this year.
Scrubb is a 24 year old righthanded pitcher who has worked mostly in relief this year for the AA Tulsa Drillers. He was an 8th round draft pick of the Dodgers out of High Point University in 2016. He has a 2.45 ERA in 47 IP this year.
UPDATE — In addition, the Astros will reportedly designate for assignment 2B/OF Tony Kemp tomorrow when they activate Carlos Correa from the injured list.
