Soriano (elbow) is expected to begin a rehab assignment in 5-to-7 days, Kevin Gorman of TribLive.com reports.
Soriano underwent Tommy John surgery in February 2020 but will soon be able to pitch in the minors as another step in his recovery process. The right-hander has been throwing simulated games recently but won't be able to be activated from the 60-day injured list until early June.
