A decision by arbitrators Frederic Horowitz, Margaret Brogan and Robert Herzog is expected Saturday.
Soroka, 23, was 0-1 with a 3.95 ERA in three starts during the pandemic-shortened season. His year ended when he tore his right Achilles tendon while pitching against the New York Mets on Aug. 3. Soroka had surgery four days later and hopes to be ready for opening day.
Decisions also are pending for St. Louis right-hander Jack Flaherty and for Tampa Bay left-hander Ryan Yarbrough.
Flaherty, 25, asked for a raise from $604,500 to $3.9 millionm and the Cardinals argued for $3 million to arbitrators Howard Edelman and Steven Wolf and Walt De Treux.
