Swanson (back) is slated to pitch his first live batting practice of spring Sunday, Greg Johns of MLB.com reports.
Swanson has been slowed by a mid-back strain suffered in January while still at home, but he was able to get through a bullpen session Tuesday without any issue. That led to Sunday's scheduled live batting practice session, and another positive outcome will likely set up a Cactus League appearance for Swanson at some point in the next week.
